Embodiment Construction
[0069] The structure and flow process of the present invention are respectively as Figure 4 , Figure 5 As shown, the specific implementation steps are as follows:
[0070] a. Before starting the parameter measurement, the original echo data of the continuous wave radar needs to be beat, fast time domain FFT, clutter suppression, slow time domain coherent accumulation, linear detection, constant false alarm detection, spectral peak search and other operations.
[0071] b. Obtain the range-Doppler domain (RD domain) data (collectively referred to as RD_data) and the result of target detection (collectively referred to as TarInfo) corresponding to the upper and lower frequency sweeps respectively, wherein the result of target detection is the index in RD_data, Through this index, the distance, fuzzy speed and power information of each detection point can be found or calculated.
[0072] Note that M detection points (i=1,2,...,M) are obtained by frequency sweeping up, and N de...
