一、背景陆军地面侦察雷达性能的长远目标是对战场上的地面运动目标进行自动分类。已经实现的有限分类方法,是把雷达的多卜勒频谱分成较低和较高的频段,以区分径向速度不同的目标。虽然这是一个重要特征,但因只有某些目标(车辆)才能获得高的径向速度,所以不能区分行人和具有低径向速度分量的车辆。 First, the background The long-term goal of the Army ground reconnaissance radar performance is to automatically classify the ground motion targets on the battlefield. The limited classification method that has been implemented is to divide the Doppler spectrum of the radar into lower and higher frequency bands to distinguish between targets of different radial velocities. Although this is an important feature, pedestrians and vehicles with low radial velocity components can not be distinguished from each other because only certain targets (vehicles) can achieve high radial velocities.
