    摘要: In an acquisition radar system of the type in which the antenna scans in a multiple-bar raster scan pattern, signals of different sets of characteristics, e.g., different PRF''s, are transmitted on adjacent bars. The elevation bar spacing is chosen to be less than 0.5 X theta b where theta b is the antenna 3dB elevation beamwidth so that any target within the pattern is illuminated by the signals of the different PRF''s.
