Embodiment Construction
[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that, in the drawings or descriptions of the specification, similar or identical parts all use the same figure numbers. Implementations not shown or described in the accompanying drawings are forms known to those of ordinary skill in the art.
[0024] Considering that there are only moving target signals in the echo data processed by ground stationary targets and clutter cancellation, and the number of moving targets in the observation scene is limited, the echo signals of moving targets meet the requirements of sparsity, so compressive sensing is adopted In theory, imaging and parameter estimation are performed on the echo signal after data compression. Compressed sensing theory points out that if the s...
