Embodiment Construction

[0017] refer to figure 1 . The automatic test of the main performance indicators of the pulse measurement radar, firstly, the radar signal processor, the radar target simulator, the radar azimuth servo controller, the radar pitch servo controller, the radar terminal display and control computer and the radar data processing computer are connected to the radar receiver. They are connected through a communication network switch to form an automatic test system under the unified control of the radar terminal display and control computer.

[0018] Under the unified control of the radar terminal display and control computer, the radar target simulator generates three high-frequency signals with different amplitudes and phases according to the simulated target characteristics, which are amplified and filtered by the high-frequency receiver and intermediate frequency receiver of the radar receiver Processing, the radar signal processor performs intermediate frequency sampling, echo ...

Abstract

The invention provides a method for automatically testing main performance indexes of a pulse instrumentation radar, which is to connect a radar signal processor, a radar target simulator, an azimuth and pitch radar servo controller, a radar terminal display and control computer and a radar data processing computer through a communication network exchange to form an automatic test system under the uniform control of the radar terminal display and control computer, wherein the radar signal processor, radar target simulator, azimuth and pitch radar servo controller, radar terminal display and control computer and the radar data processing computer are connected to a radar receiver. Such automatic tests as receiver magnitude-phase consistency, receiver band width and dynamic range of the radar, and main performance indexes of servo maximum tracking speed (azimuth and pitch), servo maximum tracking acceleration (azimuth and pitch), servo step response characteristics and servo band width and the like are realized by adopting the radar target simulator and a special test program. The test results of the performance indexes are given visually, so that the estimation and judgement to the radar performance index are greatly convenient; and convenient detection ways are provided to guarantee the radar to keep a well state and available at any time.

Description

technical field [0001] The invention is used for the automatic test of the performance index of the pulse measurement radar. Background technique [0002] Pulse measurement radar has been used as a trajectory external measurement device for satellites and rocket launch ranges in China for more than 20 years. Whether the working status of the radar is normal and whether the indicators meet the design requirements, the traditional test is usually carried out by manual measurement and instrument measurement, often due to the inconvenient test, or even the lack of test conditions, especially the test of radar performance indicators in practice. Difficulty or negligence in the process of use and training leads to a vague technical state of the radar, and operators and users cannot easily find problems with the radar system, which may lead to unsatisfactory mission execution or even failure. In order to grasp the main performance of radar at any time and conveniently, and to expr...
