Cognitive radar robust sidelobe suppression method based on sequence optimization

The invention relates to a cognitive radar robust sidelobe suppression method based on sequence optimization, comprising the following steps: dividing a to-be-detected region in range resolution cells, sequentially performing transmitting-receiving joint optimization on each range resolution cell, building an objective function and searching an optimal transmitted waveform and an optimal receivingfilter; solving the objective function by adopting a loop optimization method, so that sidelobe suppression performance can meet preset requirements, namely for a first range resolution cell, a transmitted waveform and receiving filter joint optimization problem is solved, and in each iteration, the joint optimization problem is decomposed into two independent optimization problems, one is that the receiving filter (described in the specification) is optimized by a fixed waveform (described in the specification), and the other one is that a waveform (described in the specification) is optimized on the basis of a know
