Chirp lfm
WebDec 1, 2006 · Nonlinear FM (NLFM) waveforms offer a radar matched filter output with inherently low range sidelobes. This yields a 1-2 dB advantage in Signal-to-Noise Ratio over the output of a Linear FM (LFM) waveform with equivalent sidelobe filtering. WebDec 15, 2024 · Linear Frequency Modulation (LFM) pulse signal (chirp) is a widely used pulse compression signal, which obtains large time–bandwidth products by inner-pulse linear frequency modulation.
