WebMar 31, 2024 · Pulse compression (aka 'chirp') radar was invented in the 1950s by Sperry and a couple other defense contractors. It was new enough by the time the radar I worked on as a technician in the USAF that it was … WebJan 14, 2014 · For quadrature-modulated radar signals such as FM-chirps, two baseband signals, the I and Q components, feed the external modulator. These two components are generated independently and synchronously by a two-channel AWG or by two properly synchronized single-channel AWGs.

WebAug 18, 2024 · When the FFT is performed along each row (Chirp), the spectrum analysis yields the value of the beat frequency of the corresponding chirp. Let us assume that the beat frequency is represented by Bin B. If the object is stationary, then all of the rows will have a significant value and nearly the same value in Bin B [Magnitude and Phase]. small cabin mobile homes
