| 摘 要： | 由于实际地形条件很复杂，难以准确建立雷达信号多径传播模型，从而影响了米波雷达低角测高的性能。文中提出采用射线追踪法来改进雷达反射信号多径模型，使其更接近于电波真实传播路径，以期达到提高超分辨测高算法地形适应性的目的。仿真和不同地形条件下的试验结果表明：基于改进后的多径反射模型的超分辨算法在解决地形适应性问题上卓有成效。

| Abstract: | Owing to the complexity of practical terrain, it is very difficult to build the accurate multipath propagation model of radar signal and therefore the height measurement performance of low elevation target in meterwave radar is degraded. To make the model more close to the true signal radiating path and to improve the landform adaptability of super resolution algorithm, the radar reflection echo model is improved with the raytracing method. Results of emulation and testing data show that the effect of the algorithm based on the improved radar reflection echo model is highly effective in improving the landform adaptability of super resolution algorithm. |
