Universal Servo System Isolation Of Testing Method Study

Terminal guidance radar in the search and track sea-level target, the airframe bythe motor and airflow disturbances affected，radar antenna points to a certain anglechanges, which these changes directly affect the radar of regional scope and accuracy.In order to ensure the radar on a specific area search and tracking is not affected,which requires the radar servo system stable platform must ensure that the antennapoints to the spatial stability isolation to ensure that the antenna pointing with theexternal movement changes. The main subject of improvements in radar servo systemstable platform for test-based.Firstly, this paper introduces the radar servo system principles and the impact ofisolation factors. Secondly, the terminal guidance radar servo system isolation indexanalysis and evaluation of this stage dual-plane. Finally, according to the in-depthstudy of the stability of the international and domestic track the status and history ofthe platform to address the limitations of the existing testing methods in radar servosystem isolation, isolation test method to do some useful improvements: under theradar servo system isolation characteristics of the design of high-precision laser andhigh-fidelity mirrors the isolation of test systems. According to the requirements ofthe isolation of the actual test, isolation test systems software research anddevelopment is required to determine where the calculation of optical receiver tube,deviation angle, draw the trajectory, and set the scale factor can be adjustedaccordingly, as well as meet the accuracy requirements were the average probabilitycalculation.Universal servo system isolation of testing study solved a long time the servoservo system isolation manual testing accuracy, low efficiency, accuracy improveddesign has reference significance for other equipment improved test accuracy.
