Radar pulse correlation from uniformly translating targets

TL;DR

This paper investigates how high uniform target speeds affect radar signal correlation, revealing velocity-dependent effects that persist despite Doppler correction, impacting target identification accuracy.

Contribution

It uncovers the velocity dependence of radar pulse correlation for translating targets, highlighting a factor often overlooked in radar signal processing.

Findings

Correlation depends on target velocity even after Doppler removal

High-speed translation causes significant correlation variations

Implications for improving radar target identification

Abstract

Radars often use correlation of received signals with transmitted signals to identify targets. However, when a target translates at a high uniform speed, the correlation of the transmitted and received signals depends strongly on the target's velocity, even after the two-way Doppler shift has been removed. This is true whether the target is made of highly dispersive material or not.
