| 摘 要： | 由众多单元组成的固态有源相控阵AEW雷达系统,由于其不可避免的多种误差的存在,严重地影响了非自适应处理的雷达MTD性能。本文对此进行了详细分析,并导出了在系统存在阵元幅相随机误差、通道幅相随机误差时,计算雷达MTD统计性能的理论表达式,利用该式可以避开使用费时的蒙特卡罗技术而直接计算雷达的平均检测性能。通过分析与计算还表明:在强杂波环境中,AEW雷达常规MTD性能直接受到了误差的限制。

| Abstract: | Detection of moving objects by means of a phased array airborne radar is degraded by lots of available errors. In this paper, the conventional space-time cascade nonadaptive MTD performance is analyzed in detail. The formula calculating the MTD statistical performance has been derived in the presence of random amplitude and phase errors existing in the array elements and interchannels, from v/hich we can avoid using the Monte Carlo technique which expends many execution time to calculate the radar statistical performance. Theoretical analysis and computer simulation results show that the MTD performance for AEW radars is limited directly by random errors in the strong clutter environment. |
