摘要

基于多普勒分布式杂波(DDC)模型

本文给出了机载雷达杂波多普勒参数估计的性能分析.并针对多普勒扩展较小的DDC模型

提出了一种基于非线性算子的多普勒参数快速估计算法

该算法通过采样数据直接给出多普勒参数的闭式解

能够显著地减少运算量并满足实际机载雷达的应用需求.

Abstract

Based on Doppler distributed clutter (DDC) model

this paper gives the performance analysis for Doppler parameter estimation of airborne radar.Furthermore

a fast nonlinear operator (NLOP) method is also proposed to estimate clutter Doppler parameters for DDC model with modestly small Doppler angular spread.The proposed method directly gives the closed-form expressions for estimating parameters

and it may remarkably reduce the calculation amount and satisfy the real application of airborne radar.
