摘要：

为反映不同频率电磁波照射下箔条雷达散射截面的变化情况，在研究箔条云回波信号功率谱的统计特性基础上,提出了一种新的箔条散射截面数学模型。该方法表明，单根箔条散射截面频率响应特性可采用高斯分布描述,散射截面最大值为箔条的平均雷达截面积。仿真结果表明,在箔条弹设计中可用来分析不同频率电磁波照射下箔条散射截面的频率响应特性,验证箔条弹设计的合理性,具有较高的应用价值。

Abstract:

In order to show change of chaff RCS（Radar Cross Section） with electromagnetic wave of different frequency,a new mathematical model of chaff's RCS is presented by analyzing statistics of chaff cloud echo's ower spectrum. The model indicates that Gaussian distribution can be used to describe the frequency response characteristic of single chaff RCS, and its maximum is the average chaff RCS. The result demonstrates that the simulation is useful for analyzing the frequency response characteristic of chaff with electromagnetic wave of different frequency and verifying the feasibilty in designing chaff cartridge. It has a high application value.

Key words: chaff, radar cross section(RCS), power spectrum, gaussian distribution, chaff cartridge
