The issue of polar coordinate-orthogonal coordinate conversion, which is a key factor of the system, may be encountered inevitably as simulating traditional PPI radarindicator on raster scan display.
The research on the scheme of W-band coherent Doppler radar front-end is mainly about indicator of distribution and component chosen in radar front-end.
W波段连续波相参多普勒雷达前端方案的研究中，主要是根据雷达的具体指标选取雷达前端的各个部件。
