基于多普勒效应的激光危险源定位方法
Locating Method for Laser Danger Source Based on Doppler Effect
摘要
从狭义相对论原理和多普勒效应出发,导出了双天线测向定位系统接收频率变化量的理论公式,在忽略高阶无穷小量的条件下,多普勒频移为激光信号发射方向与接收机的参考方向之间夹角之差的正弦函数,在某些特殊位置,多普勒频移为零,根据零点的位置,理论上便可测得激光危险信号的来向.
Abstract
From the point of view of relativity principle and Doppler effect, the formula of changing value in receiver frequency for double antenna directional locating device is derived,. Under the circumstance of ignoring high order-small, it shows that Doppler frequency deviation is the sine function of angle between laser emitting direction and reference direction of receiver. At some special location, frequency deviation is zero. According to this location of "zero point", the danger signal direction of laser can be determined.
