Configurable memory multiplexing moving target detector and its detection method

Abstract

The invention discloses a configurable moving-target detector with memory and multiplexing functions and a detection method thereof. The problems that existing moving-target detection is poor in flexibility and high in hardware consumption are mainly solved. The configurable moving-target detector comprises a data conversion module (1), a data distribution module (2), an FFT module (3), an FIR filter set module (4), a data selection module (5) and a bit-slicing processing module (6). The data conversion module (1) converts sequence of serial data obtained through external input, then the data distribution module (2) distributes the data to the FFT module (3) or the FIR filter set module (4) for moving-target detection, the results after detection processing are selected by the data selection module (5) and then are output to the bit-slicing processing module (6) for bit-slicing processing, the bit-slicing data are subjected to sequence conversion through the data conversion module (1) and then output to the outside through the data distribution module (2). The configurable moving-target detector has the advantages of being high in flexibility and low in hardware consumption, and can be used for processing radar signals in real time.

Description

technical field [0001] The invention belongs to the technical field of digital signal processing, and further relates to a moving target detector in radar signal processing technology, which is used to enhance the clutter suppression ability and flexibility of moving target detection, and further improve the anti-jamming ability and anti-interference ability of radar signal processing. application range. Background technique [0002] The moving target detection technology is an important technology in the field of modern radar signal processing. Various filters are used in the moving target detection radar to filter out the fixed clutter and take out the echo of the moving target, thus greatly improving the performance in the clutter background. The ability to detect moving targets and improve the anti-jamming ability of the radar. [0003] There are mainly two processing methods in the moving target detection technology, that is, the fast Fourier transform FFT in the slow ...

Problems solved by technology

However, the FIR filter bank consumes a lot of hardware and is only suitable for situations with a small number of calculation points.

[0005] At the same time, after moving target detection processing, the data bit width increases, and re-storing will consume a large number of storage units, which limits the data processing capability of moving target detection
