目标斜穿雷达波瓣时信号载波的调幅特性

AM Characteristic of Signal Carriers as a Target Crossing Abliquely Radar Wave Beam

讨论了活动目标斜穿雷达波瓣时所收信号电平的变化特性,得出了“在波瓣内某点将出现最大值,其位置只与雷达相对于目标的坐标参数有关,而与目标的反射特性无关”的结论,导出了在采用小喇叭天线下求解该坐标点的超越方程,并给出了一个验证这个结论的用例。

The variation characteristic of received echo signals as a target acrosses obliquely a radar wave beam is described by means of a critical mathematic method. A conclusion obtained is that there is a maximum level at a point within the beam, and its place only dependes on coordinate parameters of the radar relative to the target, but not on its reflectivity. By the way, a transcendandental equation for the coordinates of the maximum point is derived for a small horn antenna and an example of application is given.
