[0022] see figure 1 . For the convenience of describing the content of the present invention, the following technical terms are defined at first:
[0023] Definition 1. Three-coordinate pulse Doppler radar system. In the radar system, in order to detect the spatial position of the target, it is necessary to obtain its azimuth angle, pitch angle, and radial distance relative to the origin of the radar. Pulse Doppler refers to the radar emission waveform as a pulse, which is processed through the joint processing of multiple pulses. , can achieve the accumulation of target energy, and obtain the Doppler information of the target.
[0024] Define 2 baseband data. Baseband data indicates that the signal has been downconverted and has no carrier information.
[0025] Define 3 scan cycles. The radar antenna scanning cycle refers to the time it takes for the radar to complete a complete scan of the entire surveillance area.
[0026] Definition 4 Signal processing distance quant...
