基于运动物体高阶多普勒效应的横向速度估计
TRANSVERSE VELOCITY ESTIMATION BASED ON HIGH-ORDER DOPPLER EFFECT OF MOVING OBJECT
摘要
Abstract
The one-order phase of the echo changes if there is relative radial moving between the object and the radar, i.e., the Doppler effect. The Doppler effect is widely used in radar signal processing. The transverse motion of the object cannot change the one-order phase of the echo, but the high-order phase. The high-order Doppler effect of the transverse moving target is presented and a new algorithm for obtaining the transverse velocity is given. The scalar velocity of a target moving steadily in any direction can be calculated with one-order and two-order items of the echo phase. The calculating method and simulating results are given.As the transverse speed is 900 km/h, the speed calculation error is less than 0.06% if SNR of echo signal is higher than 0 dB.关键词
