摘　　要：针对传统双基地雷达MTI处理对切向飞行目标失效的缺陷,探讨了新体制MI-MO雷达MTI处理的性能优势。首先分析了目标飞行方向对传统体制雷达MTI处理改善因子的影响,然后针对非起伏目标,导出了MIMO雷达MTI处理改善因子的计算表达式,最后进行了仿真分析。仿真结果表明,对以任意角度飞行的目标,MIMO雷达MTI处理均可获得较高的改善因子。Aiming at the shortcoming that the MTI processing of traditional bistatic radars has no efficacy in vertical flight targets, the performance advantage of MTI processing of new system MIMO radar is discussed. Firstly,the influence of target flight direction to MTI processing of traditional radar is analyzed, then the calculation expression of improvement factor for non-fluctuation targets is deduced based on MTI processing of MIMO radar,finally simulation and analysis are given. The simulation results show that MTI processing of MIMO radar can acquire higher improvement factor to targets flying at arbitrarily angle.
