摘要

毫米波系统有着较微波、红外、光学系统不同特性的优点.毫米波辐射探测技术在许多领域有着重要应用与发展.为能求得真实的目标物体亮温

从测得的天线温度数据或天线温度分布函数中反演出装甲目标的亮温分布

需解第一类Fredholm积分方程.该积分方程是一病态方程.DFP法算法是无约束最优化方法中最有效的方法之一.本文尝试用DFP法优化控制毫米波装甲目标辐射亮温

得到较为稳定的反演解.

Abstract

Millimeter wave characteristics differ from those of microwaves

infrared or optical

as well.It has some distinct advantages over microwave

infrared

or optical system.There are many significant applications and exciting developments in millimeter wave system. To calculate the brightness temperature distribution from the measured antenna temperature

a Fredholm integral equation of the first kind must be solved.This equation is ill-posed.DFP is applied to recovery of the armour target's brightness temperatures from the scanning millimeter wave radiometer data.
