Automatic test system of video auto-cancellation device based on general test platform

Abstract

The invention relates to the field of continuous wave radar technology and fault automatic test technology, particularly to an automatic test system of a video auto-cancellation device based on a general test platform. The general test platform (1) and a special adapter (2) performs bidirectional data and command transmission through an Ethernet communication interface, the special adapter (2) under the control of a test procedure set provides a test signal vector for a test of a video auto-cancellation device (3) to be tested. The automatic test system of the video auto-cancellation device based on the general test platform can efficiently and accurately complete a comprehensive test including a function and performance test, fault diagnosis and fault positioning of an emission leakage auto-cancellation device, overcomes the defects that existing test technology and method has a single function, and is limited in test precision, low in test efficiency and poor in expandability, and has the advantages of good universal performance, strong function expandability, good test replantability, high test precision and test efficiency and the like.

Description

Technical field: [0001] The invention relates to the technical field of continuous wave radar technology and fault automatic testing, in particular to an automatic testing system of a video automatic cancellation device based on a general testing platform. Background technique: [0002] Pseudo-random code phase-modulated continuous wave is a radar system with high distance resolution, high speed resolution, and low probability of interception. It has received attention and extensive research at home and abroad. Target detection, space target measurement and other fields have been widely used. However, for monostatic pseudo-random code phase-modulated continuous wave radar, no matter whether single antenna or dual antenna is used, the emission leakage is one of the important factors restricting its performance, and the automatic cancellation of emission leakage is a must-use technology, otherwise the emission leakage will be Deterioration of system performance, more serious ...
