摘要

本文从对称三角线性调频连续波雷达体制的特点出发

导出了对称三角线性调频连续波信号模糊函数

分析了它的特点;阐明了它与单斜率线性调频连续波信号和脉冲LFM信号模糊函数的区别;从模糊函数的角度分析说明了采用对称三角线性调频连续波信号相对于单斜率线性调频连续波信号可以大大提高目标的分辨力

并能消除多目标环境中运动目标的距离速度耦合现象.

Abstract

Based on the characteristic of symmetrical triangular frequency modulation continuous wave (STMFCW) radar principle

the ambiguity function of STFMCW signal is presented and analyzed.The differences between the ambiguity function of STMFCW signal and single slope linear frequency modulation continuous wave signal and pulse LFM signal are also discussed.In addition

from the property of its ambiguity function

it is indicated that using the STFMCW signal can considerably enhance the resolution and eliminate the range-velocity coupling of moving target under multi-target environments.
