The SAR sidelobe suppression method based on the parallel transceiver using orthogonal chaotic frequency modulation signal

Consider the schematic in Figure 2, where the basic architecture of the SAR parallel transceiver system using Bernoulli FM signal is shown. There are three steps: Bernoulli sequence is introduced to the transmitter to generate N chaotic FM signals orthogonal to each other; the echo signal is firstly orthogonally separated and then compressed to acquire the imaging result, respectively; the final imaging result can be obtained from an average of those results acquired in the last step.
