Calculation method of critical radar cross section of low pulse repetition frequency PD radar

  • A solution to the problem of calculation on critical radar cross section (RCS) of low pulse repetition frequency (LPRF) PD radar was given. The critical elevation method was adopted to deal with the unknown radar parameters, and combine those parameters into a radar character constant. When the target′s signallocated in sidelobe clutters area, the problem was dealt with by treating the sidelobe clutters of LPRF PD radar as noise. While the target′s signal located in main beam clutters area, the problem was dealt with by adding the equivalent clutters RCS into the critical RCS of sidelobe, the displaced phased center antenna(DPCA) technology′s effect on critical RCS was considered too. All of which complete the critical RCS calculating method in the whole spectrum of LPRF PD radar, and the method could be used to solve the problem on detection probability of target. At last, an example of E-2C detecting a target was given.
