在空域监视过程中,有时希望对目标进行分类。在某种程度上,目标的分类,一般可以根据经典的雷达测量方法所测得的飞行轨迹来实现。下面介绍一种可以测量单个目标雷达横截面侧向变化的方法。在采用这种方法时,假定目标至少在几秒钟内按匀速直线飞行,并且能产生一个切向分量。由于飞行路线通常是直线的,而且采用雷达网观察目标,所以总是能得到切向分量。这样,上述的限制条件就不是很苛刻了。这种方法特别适用于电控扫描雷达。 In the process of airspace monitoring, it is sometimes desirable to classify the target. To some extent, the classification of targets can generally be based on the flight path measured by classical radar measurement methods. Here’s a way to measure the lateral variation of a single target radar cross section. In this method, it is assumed that the target will fly at a uniform speed for at least a few seconds and produce a tangential component. Since the flight path is usually straight and the radar network is used to observe the target, tangential components are always obtained. In this way, the above restrictions are not very harsh. This method is particularly suitable for electronically scanned radars.
