| 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 echos power 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. |
