    摘要: A method and apparatus to determine angles .theta..sub.1 and .theta..sub.2 between paths of two sets of reflected radar waves and a radar boresight utilizes the electrical angles .beta..sub.1 or .beta..sub.2 and two successive radar target observations. One set of radar waves may travel a path from a target and the second set may travel a multipath from the same target. Alternatively, the two sets of radar waves may follow direct paths from two targets. For coherent radar hardware, signals from two halves of an array are processed through a linear coherent receiver, analog-to-digital converter and processing unit with associated memory. The memory contains a database and program which calculates the electrical angles .beta..sub.1 and .beta..sub.2 and angles .theta..sub.1, and .theta..sub.2. For non-coherent radar hardware, mixers, a phase detector and two magnitude detectors are substituted for the linear coherent receiver.
