Learn how you can use digital beamformers to improve the performance and functions of radar systems.
The MATLAB Tech Talk series on radar covered how to use radar to determine range, range rate, and angle of arrival of a target, and even multiple targets.
The MATLAB Tech Talk series on the basics of digital beamforming covered how to use sensor arrays with multiple RF chains to have more control over the shape of the beam in ways that maximize signal and minimize interference. Plus, the use of sensor arrays with multiple RF chains also allows for multiple independently steered beams from the same array.
So, the question is: What benefits can you get out of having a radar system that has the ability to generate multiple beams of various different shapes? Find out in this tech talk.

Began learning about radars on my own and this was fantastic!! Needs more views

Can you help me with my project for drone detection radar? What kind of input it will take to do the digital beam forming and where we ll use this digital beam forming step in dron detection radar signal processing?

Hello, thank you very much for this amazing explanation. Could you please suggest a source to understand the difference between beam switching and beam steering? Or maybe you can directly explain it.Thank you very much in advance

Hi great video, 5:50 and forward is a bit misleading. a narrow beam has a much better resolution and SNR (more energy) but it's not used to pinpoint the location of a target. for this you are using a monopulse, which means you have a regular beam transmitting to a specific location and receiving beams around that same transmitting beam, now you can compare the power coming from each of the RX beams and calculate the target location in relation to the TX beam. The mistake in the video is that you go to a narrow beam when you don't need to. Narrow beams are mainly used for long range surveillance in modern radars.

You can only get so much accuracy out of monopulse signal with a wide volume search beam tho. By using the tighter beam you get additional accuracy out of it for getting the pencil beam tracking pulses on him. What i think he was trying to get at here was by using that pattern of tighter beams around the point of the volume search detection. You get the accuracy of the tighter beam but also potentially getting detections on other targets around the primary detection that weren't seen with the wider beamwidth.

@@josephrosenbaum3343 You are correct that by using a narrow/pencil beam you would get a better spatial resolution especially with TWS tracking in Monopulse. I didn't see the vid again so I'll guess my idea was that you don't waste the most important Radar resource which is time. Why fire more beams and wait for the return if you can cover more space and still get enough data for the purpose of your Radar?
