Abstract针对稀疏阵的欠采样会引起动目标检测盲区的问题,基于星载GMTI(ground moving targets indica-tion)稀疏线阵雷达,分析了多载频稀疏阵雷达的系统模型和空时自适应处理(space time adaptive processing,STAP)的基本原理,考虑了非周期阵列对减少盲区的作用。仿真结果表明采用多载频模式可有效改善稀疏引起的动目标检测盲区。
Other AbstractGround moving targets indication(GMTI) is an important function for spaceborne sparse array radars.To solve the blind-zone problem of detection due to the undersample of sparse array,the basic principle of space time adaptive processing(STAP) and the model of sparse array radar systems with linear array and with multiple carrier frequencies are analyzed.At the same time,aperiodic subarray spacing is considered to mitigate the blind zones.Simulations shows that the MTI blind zones caused by sparse aperture has been effectively reduced by using multiple carrier frequencies.
