摘　　要：首先对直升机旋翼的雷达回波进行建模与分析 ,在此基础上分析了雷达探测悬停直升机的可能性 ,提出了一种适用于所有直升机类型的多扫描周期积累检测系统方案 ,讨论了可能影响其检测性能的因素 .The characteristics of the radar echo of helicopter rotor blade are analyzed firstly, then the possibility to detect a hovering helicopter by the main rotor echo (MRE) is analyzed. As a result, a multi-scanning-periods accumulate detection (MSPAD) strategy for detecting hovering helicopter against ground clutter is proposed, which is the same with all kinds of helicopter, and the factors that may influence the detection performance are discussed.
