| 摘 要： | 本文用蒙特卡罗计算机仿真法研究振荡信号频率起伏对脉冲雷达性能的影响。由于现代脉冲雷达存在明显的混叠效应,和由放大链引入附加噪声等情况,使其仿真方法要比连续波时复杂得多。本文提出的五阶ARMA滤波以及间隔取数据的办法可较好地解放混叠效应的仿真问题。文末举脉冲多普勒雷达为例,介绍仿习具体步骤和仿真结果。

| Abstract: | In this paper, the Monte-Carlo computer simulation is proposed for investigating the effect of frequency fluctuation on the pulse radar performance. This simulation is much complicated than that of a CW radar because in most radar the serious aliasing effect is existed, and random noise is overlaid in its amplifier chain. In order to realize this simulation, 5th power power ARMA model filtering is adopted and the sampling rate can then easily be reduced. Finally, a practical example of simulating the performance of a pulse doppler radar is given. |
