摘要
在无源探测中,对距离的获取是一个关键问题。本文利用线性天线阵,提出了一种基于相位差的差的单站瞬时无源定距技术,并就这种定距技术的精度、解相位模糊、长基线测量精度、长基线情况下相位差的测量、通道校正等一系列关键问题进行了分析。研究表明,本文提出的定距技术在现有工程技术条件下是可行的。
Acquiring range is a key problem in passive detection. A kind of single observer instantaneous passive ranging technology is proposed based on difference of phase difference from linear array antenna. The ranging accuracy, resolving phase ambiguity, measurement accuracy of long baseline, measurement method of phase difference and channel calibrated technology are analyzed. Researches show that the ranging technology proposed in this paper is feasible under existing engineering technology condition.
