WebJun 8, 2003 · Based on multicarrier chirp signal (OFD-LFM), a spectrum effective integrated waveform with multiple symbols on each pulse is proposed and demodulation algorithm is work out and results show that optimal demodulated can be achieved simply by addition, subtraction and matching filtering, and the ambiguity function won't be … WebThe most important characteristic of chirp waveform is its correlation property. When long duration chirp signal with bandwidth B correlates with itself, it will produce a result with a sinc function that has duration equivalent to 1/B. In radar, it means transmitted signal correlated with received echoed back cluttered signal. In modern radar,
