摘要
飞机激光雷达散射截面的测量, 对于研究飞机激光散射特性以及评估探测系统至关重要.本文介绍了飞机激光雷达散射截面测量理论, 设计了飞机激光雷达散射截面测量装置和测量方法, 并通过实验验证了该装置与测量方法.在全尺寸真实飞机试验与测量过程中, 通过对原始数据高斯补偿与背景修正, 获得了误差小于7%的飞机激光雷达散射截面数据.实验结果表明,本文提出的飞机激光雷达散射截面测量与分析方法是正确的和有效的.
Abstract
The measurement of aircraft LRCS is of crucial importance for the detection system evaluation and the characteristic research of the laser scattering from aircraft. A brief introduction of the measuring theory of the laser scattering from the target is presented in this paper. By analyzing the measuring condition in outfield test, the laser systems and test steps are designed for full size aircraft LRCS and verified by the experiment in laboratory. The processing data error 7% below is obtained of the laser radar cross section by using Gaussian compensation and elimination of sky background for original test data. The of measurement and analysis proves that the proposed method is effective and correct to get laser radar cross section data in outfield test.
