Design of Compatibility of Stepped Frequency and Pulse Doppler

研究基于圆锥扫描体制下,频率步进与脉冲多普勒(PD)复合的兼容性设计.从理论上分析了频率步进与脉冲多普勒信号的选择方法,探讨了两种体制转换的工程算法及其实现,并通过外场试验对毫米波导引头系统在频率步进和脉冲多普勒模式下分别对静止目标和运动目标的最大作用距离与圆锥扫描测角进行实验验证,结果表明频率步进与脉冲多普勒复合体制下的静动目标距离分辨与测角是可行的.

The compatibility of the stepped frequency mode and pulse Doppler mode has been studied based on the conical scanning system. The signal selection between stepped frequency and pulse Doppler was analyzed in theory. The arithmetic and the application of the conversion between the two systems were discussed. Outside test was validated about high rang resolution and an- gle measure of MMW seeker under the composite system of stepped frequency and pulse Doppler. The result shows that the high rang resolution and angle detect for rest and move target is feasible based on the composite system of stepped frequency and pulse Doppler.
