Abstract星载雷达高度计依靠对海面回波的跟踪,测量卫星到海面的距离.卫星平台的姿态角会显著影响高度计的回波形状,从而带来指向误差.推导了利用高度计回波跟踪反演姿态角的2种算法(两点法和线性回归法),并对它们进行了误差分析.然后通过蒙特卡洛仿真评估了算法的性能,并对理论分析进行了验证.最后,对算法的实现进行了进一步讨论.
Other AbstractAltitude angel can influence the echo waveform of radar altimeter severely,so it is an important parameter in altimeter tracking , and there are several approaches to estimate it.In this paper the authors describe two algorithms based on altimeter waveform tracking and carry out the accuracies of them.Afterwards,the authors implement some Monte2Carlo simulations,consider the performance of the algorithms and validate the conclusions of theoretic analysis.
