摘要:

本文研究了脱靶量测量中的雷达回波数据的实时压缩问题，通过对作匀速直线运动目标的多普勒信号特征的分析，提出了一种基于离散余弦变换（DCT）的多普勒信号的变换域压缩算法，并讨论了根据重构信号由高分辨率谱估计及非线性最小二乘拟合进行脱靶量测量的问题。

A Real-time Compression Algorithm for Radar Echoes

()

Abstract:

In this paper, a real-time miss distance-oriented compression algorithm for radar echoes in transform domain is studied. A DCT-based compression algorithm in transform domain is proposed in light of the characteristics of the Doppler signals. The miss distance measurement is also discussed by the way of high resolution spectral estimation and nonlinear optimizing algorithm from the reconstructed signals.
