Abstract

The invention is suitable for the technical field of radar signal processing, and provides an MIMO radar signal processing method and device, terminal equipment and a storage medium, and the method comprises the steps: obtaining a linear frequency modulation signal corresponding to a sampling point through an MIMO radar; performing autocorrelation and windowing processing on the linear frequency modulation signal in sequence to generate a target filtering coefficient corresponding to the linear frequency modulation signal; performing quantization processing on the linear frequency modulation signal and the target filtering coefficient to obtain a quantified linear frequency modulation signal and a quantified target filtering coefficient; and determining a target signal according to the quantified linear frequency modulation signal and the quantified target filtering coefficient. According to the method, the filtering effect of the chirp signal is improved through the filtering coefficient, the radar performance and the target detection efficiency are improved, and the development cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of radar signal processing, and in particular relates to a MIMO radar signal processing method, device, terminal equipment and storage medium. Background technique [0002] The radar mainly emits electromagnetic waves to irradiate the target and receives its echo, thereby obtaining information such as the distance from the target to the electromagnetic wave emission point, the distance change rate (radial velocity), azimuth, and height. Due to its all-weather and all-time characteristics and certain penetrating ability, it is widely used in the detection distance. [0003] At present, in the prior art, the transmission power of electromagnetic waves is mainly improved by improving hardware, thereby improving the performance of the radar and the efficiency of target detection. For example, choose an FPGA device with larger RAM. [0004] However, the above method of improving hardware will lead to high devel...
