摘　　要：针对单站单波段红外被动测距问题,对红外被动测距原理及其实现进行了论述;对影响单站单波段被动测距精度的因素进行了分析,提出了一种基于线性预测的被动测距方法.该方法能对测距中出现的奇异值进行有效的抑制,从而降低测距误差.利用外场实测中、长波红外图像对该算法进行了验证,并对测距结果和误差进行了详细分析.he theory and the implementation of the mono-station and single-band IR passive ranging were discussed,and the factors affecting the ranging accuracy were analyzed.A kind of method was proposed based on the linear predictor.This method can suppress the singular range values and reduce the ranging error effectively.Finally the method was validated respectively by the middle wave and long wave IR data obtained from the airplane,and the ranging results and errors were analyzed.
