Modemized Method of Processing Low-Based LFM Signal Burst
In the processing of low-based linear frequency modulated (LFM) signal it’s not possible to reach the side-lobes level (SLL) that corresponds to the weight function in matched filtering and weighting, due to Fresnel pulsations of spectrum. Method of return pulsations allows to obtain corresponding SLL for a single pulse, however, the form of spectrum of LFM signals’ burst makes this method inapplicable. We suggest a method of a burst of LFM signals processing based on “return pulsations” method, which allows to obtain SLL that corresponds weight function.
