ChirpRfFreqSlope Changes Overview

In this content, different settings of ChirpRfFreqSlope parameter are explored with values of 10, 35, 75, and 140 MHz/us. The parameter variations are analyzed within a radar system configuration involving channel settings, chirp timing, frame configuration, signal processing chain, and more. The impact of altering ChirpRfFreqSlope on system performance and characteristics is examined through practical testing and description of results.
