01 Propagation Model Validation INTRODUCTION 15

Introduction to and overview of field tests to validate the propagation model I used for real-time ECM effectiveness feedback for two applications:
1) counter-RCIED ECM Protection Range Estimator, and
2) cognitive ship defence against missile attack, specifically jog detection.

i really like your software. I have done similar before but only by walking down range and recording the power at various frequencies using a spectrum analyser and writing down the observed power at each frequency. far too laborious!

Thanks - I did the same at first and found it frustrating, not much in-hand after all the work of setting up and operating equipment, and not so easy to get time on a test range. Real insights can come from playback of recorded spectra in a power vs. range graph, insights that I don't know how to get any other way - even years later by noticing features I didn't know about when the measurements were made. Example: I can see leaves on trees in spectral measurements, and the difference between winter and summer testing; I found that long after the data were recorded. And recently I noticed the "tennis courts" measurements (kzbin.info/www/bejne/aGTJl5lvYtyBb8U) have very little temporal noise, so that's more evidence of leaves/side-scatter effects, years later. And the digital recordings can be used for lots of other things, forever. Example: Create a virtual test range, a coax cable lab bench test range, with some limitations. Example: Compare different test ranges around the world for suitability of experiment XYZ. Example: Compare test ranges with similar real-world in-theater data, if it can be obtained. And there's a reason to.
