摘要:
针对高速交会毫米波探测器在近场区由于自旋导致的微多普勒效应、信号间断问题,提出了毫米波探测器自旋微多普勒信号仿真方法。该方法从构建弹丸交会段的自旋水平运动模型出发,采用刚体姿态分析及点波束回波分析法,精确分析此飞行条件下的回波特性。仿真结果表明,由旋转导致的探测器回波多普勒频率、功率呈周期性变化且与旋转速度、载体形状有关。仿真方法有助于对复杂运动状态下探测器回波信号的分析与建模。
Abstract:
To solve the problems about millimeter-wave detector in near-zone affected due to the spin echo signal generating micro-doppler effect and signal discontinuity, a spin micro doppler signal simulation method for millimeter-wave detector was proposed. This method was based on the establishment of the spin horizontal motion model of projectile in rendezvous section. By using the methods of rigid body posture analysis and spot beam echo analysis, the character of the echo under this flight condition re analyzed precisely.The simulation results showed that the Doppler frequency and power of the detector echo caused by rotation changed periodically and were related to the rotation speed and the shape of carrier, the simulation method was helpful for the analysis and modeling of echo signals in the complex motion state of detector.
