摘　　要：强海杂波是主动雷达导引头在大入射余角条件下目标检测面临的严峻问题。在该条件下,给出了一种有效的导引头舰船目标检测技术,并分别针对其应用雷达回波前沿检测技术和采用脉冲压缩加多普勒锐化技术的检测性能和约束条件进行了分析。分析表明,在一定条件下,能够实现弹道导弹大入射余角攻击条件下,导引头在强海杂波下的目标检测。When an active radar seeker is used to detect the ship target via a large incidence angle,the heavy sea clutter will seriously degrade the detection performance.This paper proposes an efficient ship target detection technique when a large incidence angle is occurred.The performance and constrain of radar echo leading edge detection and pulse compression and Doppler beam sharpening technique are analyzed.The analysis indicates that the technique proposed above is effectiveness in some given condition when the ship target is in the large incidence angle.
