Drone Tracking Radar: Part 7 Longer Range and MTI Processing

[@C.DanielBoschen]

Awesome work Jon!

[@jonkraft]

Thanks Dan! It was great seeing you at GRCON, and I learned a lot of DSP and Python from taking your classes in 2020. Thanks! For everyone else, please check them out here: www.dsprelated.com/courses

[@renatomsgomes]

​@@jonkraft make more videos this is defenitly far more interesting that at the starting point. Its working and making great improvements

[@WyrdieBeardie]

All of this is very exciting. It is great to see these topics made so accessible! Thank you so much.

[@egeres14]

I'm glad to see another video!! I haven't seen anything like your radar series anywhere else, thank you so much for putting together this material and helping so many people understand this technology better 💪🏻

[@maverick9708]

The sequel we wanted but didn't deserve

[@forzascuderia1712]

Wow, your videos are amazing Jon! It’s not easy to come across videos that clarifies radar processing! Have you thought about doing some advanced processings like STAP, or Kalman Filter?

[@AerialWaviator]

Another excellent video with solid resources. Really appreciate sample sample data sets being made available for people without hardware access to learn and experiment. I do hope you continue to add to this series as time and topics permit.

[@harristidwell4818]

You and your team are crushing it! Always love the videos.

[@philorkill]

Super cool project and results. Thank you for sharing!

[@torgjerde4283]

Awesome work. Thanks for sharing Jon.

[@tranguyen758]

Awesome. I am looking forward to seeing your next videos.

[@norm1124]

Great idea to provide the data.

[@wouldntyaliktono]

These MTI algorithms remind me a lot of convolutions in a neural network to identify edges or corners in an image.

[@sin7wu]

You're the best!

[@darrenconway8117]

Good to see you back. Not sure if you have covered this, but have you considered applying cross correlation to dig out the signal from under the noise? Once you have a usable return, you could then apply a Kalman filter to track the drone.

[@jonkraft]

Thanks! I'd love to see your idea implemented. Give it a try! The data is here: ez.analog.com/adieducation/university-program/m/file-uploads

[@KetanMaheshPatil]

Thanks Jon, Great Information. Could you please also make a video on methods to get the elevation data.

[@jonkraft]

Thanks! Yes, I'm going to start a new series soon where we can steer in elevation and azimuth.

[@geoffmatthews6283]

You showed an X band horn antenna & spoke about the supplier. I have not found a link to this, could you please point us in the right direction?

[@jonkraft]

Yes, you're right. I just added the link into the description. I can only find it on ebay.

[@usman710]

You can make one yourself,

[@GiC7]

Thanks, great information

[@wseanovostok]

🎉🎉🎉 new video

[@jonkraft]

Thanks Anton! The stuff you're doing with Pluto and radar is amazing. Слава Україні!

[@wseanovostok]

@@jonkraft thank you Jon , your videos motivates to move forward

[@user-mx6nb1lh9z]

Thank you!!

[@ahmedmoustafa6829]

No Kalman filters?

[@MrFaaaaaaaaaaaaaaaaa]

it would be cool to save drone telemetry data sync'd with the radar feed :) we could really juice up our filters haha

[@hello81642]

Do you have a tutorial on sound triangulation. Identifying where sound is coming from using microphones placed in various places? That would be cool

[@viper316]

Great video. How to find the ground spend and altitude of the flying object? Can you use stereo-like radar technique to find them?

[@Jotaromilktea]

Any suggestions for a moving base station?

[@kentswan3230]

The tests show that Doppler radar returns for a stationary target or target moving perpendicular to the radar illumination axis do not generate significant returns. Given the subtractive corrolated chirp suppressing the background returns I'm wondering if a diffeerntial range target tracking vs background range signaling could handle those cases.

[@jonkraft]

Give it a try! The data is here: ez.analog.com/adieducation/university-program/m/file-uploads

[@kentswan3230]

@@jonkraft Unfortunately no real ability to do so and . The form you use is essentially a target on a cross vertical plane. I guess what I'm proposing is essentially creating a 2d horizontal planar correlation to highlight targets in a positional map using sort of a synthetic dopler. If multiple mapping planes were generated, then an stationary ariel target is above ground level and should still show against the suppressed background... maybe.

[@MagendranSambasivam]

The phase shift between adjacent chirp pulses carries the Doppler information. Will it get affected if we apply phase alignment in the 2 pulse canceller?

[@jonkraft]

It's a good thought, but no, the velocity is not affected by the 2 pulse canceller. You can see that in the plots where I show both 2 pulse and no pulse (regular). The velocity stays the same. The velocity is the change in distance (beat freq) from one pulse to the next.

[@ys1976]

Excellent video. For some reason, there's a bug in the technical support page. I can't post a question there, so I'll post it here : regarding the HMC451 Power Amplifier : does it arrive from Analog Devices with all the connectors structure shown in the video, or were they ordered separately? I've only found them for order without the connectors. Thanks in advance.

[@jonkraft]

Yes, the SMA connectors come installed on the eval board.

[@Shocker99]

So... when is the next video? 😃

[@wildgoosechase72]

So ballpark how much would the project cost?

[@911canihelpu]

300-500ish with the cheaper antenna

[@fun5259]

Hello, can you tell me in which program CN0566 can be modeled and in which one did you model? maybe in AWR Design Environment V15?

[@jonkraft]

That is a really good question. Unfortunately, I don't have any RF models for the Phaser. There is a Keysight SystemVue model for the ADAR1000. But there really should be an RF model for the whole thing....

[@Yakroo108]

👍👍👍

[@charlesurrea1451]

How about ground Contour

[@extraordinay]

Could you perhaps add some more practical use to the radar, like a motor that follows the drone?

[@jonkraft]

Yes, that's hopefully where we end up when we finish the phased array implementation. But instead of a motor, we'll electronically steer the array.

[@petrowi]

What would the whole system cost without the Raspberry Pi? Can we attach it to the 3ft span/15" prop drone I'm building?

[@jonkraft]

Details on the phaser kit, included price and availability are here: www.analog.com/cn0566 There's details on size and construction on the wiki page. But it's not intended to be used in any production. It is a learning/exploration platform for phased array radar concepts and prototyping.

[@pcchris02]

Waiting for someone to combine this with the airsoft or paintball auto turrets for the CIWS-at-home

[@kozlovskyi]

How much time do I need to learn PCB design for RF devices?

[@Tubs737]

7

[@nickst2797]

Ιs is this the last video on the series?

[@jonkraft]

I hope so! But if people do implement other algorithms with that radar data, then I will do a video on their contributions. That would be cool to learn. But otherwise, I'm moving on to some things with Pluto and phased array beamforming.

[@justme-n-gracie]

"indictor"?

[@jonkraft]

Ha, whoops! Thanks for catching that. Fixed now.

[@patrickpoirier1877]

Hello Jon, Great Video as usual, I just wrote to the Antenna Supplier to arrange shipping. May I ask if you could provide us, your followers, with a discount code for the CN056 to make it a little more affordable ?

[@jonkraft]

Thanks! Unfortunately, I don' have any control over Phaser/CN0566 pricing. But there's a lot you can do with Pluto, and I think the next couple videos will show some comms and radar labs with Pluto.

[@charlesspringer4709]

Huh. "Two Pulse" looks like a high pass spacial filter. It is the derivative (difference) in image processing or image reconstruction from projections, etc. I must make this! Maybe lower frequency with a HackRF.

[@jonkraft]

Yes, please give it a try! And let me know how it goes!

[@charlesspringer4709]

@@jonkraft I wonder if you did not do the two pulse processing and just did high pass on the output image. A simple Gaussian hi-pass kernel. Would it be the same? Oh, wait. The data is available :-) (If it worked you could do it on a graphics card easily)

[@jonkraft]

Yes, give it a try!

[@MrIanspeed]

Chirp2p or not Chirp2p, that is the question...😅
