Abstract

The invention provides a constant false alarm detection method and device for radar detection, electronic equipment and a storage medium, and belongs to the technical field of radar signal processing, and the method comprises the steps: obtaining the sample data of at least one radar frame, and generating a corresponding distance-Doppler scattering center energy matrix; for each radar frame, based on the corresponding distance-Doppler scattering center energy matrix, determining a truth value of noise energy estimation of each distance unit, calculating a target noise energy estimation coefficient of each distance unit and a target detection threshold coefficient of each distance unit, and calculating a reference detection threshold value of each distance unit; and performing constant false alarm detection on the Doppler dimension scattering center of the radar detection data based on the reference detection threshold value of each distance unit. According to the invention, target detection under a non-uniform clutter distribution condition can be realized, and ideal detection performance can be achieved.

Description

technical field [0001] The invention relates to the technical field of radar signal processing, in particular to a constant false alarm detection method, device and electronic equipment for radar detection. Background technique [0002] Constant False Alarm Rate (CFAR) technology is a technology in which the radar system discriminates the signal and noise output by the receiver to determine whether the target signal exists under the condition of keeping the false alarm probability constant. [0003] In the process of large-scale installation and use of radar, in the face of complex application scenarios, the distribution of clutter or noise energy is diversified, and the classic constant false alarm detection algorithm (CFAR) is only suitable for targets under uniform or partially non-uniform clutter distribution conditions Detection, the ideal detection performance cannot be achieved under the condition of non-uniform clutter. Contents of the invention [0004] The inven...
