Target Angular Scintillation Measurement of Wide-band Range Comparison Monopulse Radar in Anechoic Chamber
The range comparison monopulse radar measures angles by comparing the range of the difference-channel signals with the range of the sum-channel signal. Practically, It has been generally accepted that what the radar measures is not the directions of the target, but angular glint errors. In order to realize this characteristic of radar target, a wide-band radar simulate system based on CATR (Compact Antenna Test Range) was used in this researching. By making use of high-frequency phase shift correcting algorithm, the effect of test errors caused by the difference-sum channels non-equilibrium was weakened. With paying close attention to the complex dimension expend radar target, an algorithm including HRRP (high resolution range profile) method was used to extract and describe the nicety of angular scintillation. At last, the scintillation measurement results of double balls union and airplane model have been laid out.
