摘　　要：在战场侦察雷达的应用中,对各种地面目标的分类识别,一直是一个重要课题。本文针对人员、履带车、轮式车、直升机和炸点的回波特性作了讨论。研究了人员、车辆目标特征谱多普勒响应的特点,提出了一种利用人员目标的多普勒响应的波动特性,结合目标的反射幅度来区别人员和车辆的目标识别方法。研究了轮式车和履带车的多普勒谱分布特性,提出了利用两种目标的多普勒带宽特性来区分轮式、履带车辆的方法。研究了炸点目标的多普勒谱分布特性,提出了利用炸点目标与普通目标的多普勒分布差的区别进行分类的方法。Classification of ground targets in battlefield is important for battlefield surveillance radar.Characteristic of echoes of personnel,wheeled vehicle,tracked vehicle,helicopters and impact point is analyzed.Features of Doppler response of eigenvalue spectrum of personnel and vehicle are studied;a target classification method to discriminate personal and vehicle is proposed based on Doppler response fluctuation and reflective amplitude of personnel targets.A method to classify wheeled and tracked vehicles based on characteristic of Doppler spectrum distribution is studied.A method to discriminate impact point from common targets is studied based on difference of Doppler spectrum distribution.
