Abstract

The invention discloses a radar target tracking recognizer based on DSP, which comprises a transmitter, a receiver, a digital signal acquisition unit and a digital signal processor, and is used for receiving a digital difference frequency signal transmitted by the digital signal acquisition unit, and carrying out fast Fourier transformation FFT to acquire a power spectrum of the difference frequency signal and acquire the radial distance of a radar target according to the position of the power spectrum of the difference frequency signal. Compared with the prior art, the radar target tracking recognizer based on the DSP can realize quick and real-time detection and tracking for a moving target, enhances the target recognition performance of radar, does not need to adopt a special chip, is favorable for lowering the production cost, and has important productive practice significance.

Description

technical field [0001] The invention relates to the technical field of radar, in particular to a radar target tracking recognizer based on DSP. Background technique [0002] Moving target detection and tracking is to detect, extract, identify and track the moving target, obtain the moving parameters of the moving target, such as position, speed, acceleration, etc., and then perform further processing and analysis to realize the understanding of the behavior of the moving target. Complete higher level tasks. [0003] With the continuous development of radar technology, millimeter-wave radar target recognition has become an important direction for the development of modern radar systems. The functions of millimeter wave radar not only include conventional detection, positioning, search and tracking, but also a series of other new advanced functions, such as target imaging, recognition, terrain mapping, etc. Millimeter wave radar usually transmits and receives broadband signa...
