WebDec 20, 2016 · I perform pulse compression by applying a matched filter of the simulated chirp waveform and recording the location and power of the peak. Often times the recorded signal has a Doppler shift, so there is … WebJul 24, 2024 · What you are seeing is the output of the autocorrelation, which is what the matched filter produces. When noise is added, the matched filter still is used to attempt and extract the highest SNR possible. The output now might be distorted and may not look exactly like what I've shown. how many dollars is one billion pennies
