Description

technical field [0001] The invention relates to the technical field of radar data processing, in particular to a VPX bus-based vehicle radar timing generation system and method. Background technique [0002] In phased array radar, each subsystem of the radar, such as the transmitting subsystem, receiving subsystem, and signal processing subsystem, needs to work together in an orderly manner under a unified timing signal beat to jointly complete the target detection task of the radar. Stability and reliability are crucial to the stability of the radar's overall detection capability. The generation mechanism and method of the timing signal of the radar machine determine the quality of the timing signal to a large extent. [0003] In order to meet the needs of increasing detection distance and continuous improvement of detection accuracy, modern phased array radars have continuously increased requirements for the processing capabilities of the signal processing platform archit...
