Abstract

In view of the difficulties of testing the range accuracy of infrared phase range finder under field conditions, this paper establishes a simulated testing model. This model receives the infrared wave emitted by the phase range finder, and then makes spectrum analysis on the sampled received wave to obtain its initial phase. Therefore the initial phase of the local oscillation source in the phase range finder can be estimated. According to the preset simulated range value the initial phase of the simulated echo can be calculated and set. By examining the response after the phase range finder receiving the simulated echo, it is possible to judge whether its range accuracy is up to the technical specification. This paper presents functional simulation experiments, and the results confirm the feasibility of the simulated testing system model.
