Embodiment Construction
[0025] The invention provides a radar target simulator calibration system, which is used to solve the problem in the prior art that the radar target simulator cannot be accurately evaluated due to the complexity of test signals.
[0026] For realizing the above object, technical scheme of the present invention is:
[0027] A radar target simulator calibration system, including a test signal generation part, an echo signal receiving part and a data processing part;
[0028] When testing the radar target simulator under test, the test signal generation part sends a test signal to the radar target simulator under test, and the echo signal receiving part receives the echo signal of the radar target simulator under test;
[0029] The data processing part is used to: obtain the echo signal output by the radar target simulator under test; adopt the statistical test method to evaluate the consistency between the echo signal of the radar target simulator under test and the standard ech...

The invention provides a radar object simulator calibration system comprising a test signal generation portion, an echo signal reception portion and a data processing portion; when a tested radar object simulator is tested, the test signal generation portion sends a test signal to the tested radar object simulator; the echo signal reception portion receives an echo signal from the tested radar object simulator; the data processing portion is used for obtaining the echo signal outputted by the tested radar object simulator; a statistics inspection method is employed to evaluate the consistencybetween the echo signal of the tested radar object simulator and a standard echo signal, thus obtaining an evaluation result of the tested radar object simulator; the standard echo signal is obtainedaccording to the test signals and a standard mathematics model of the tested radar object simulator. The statistics inspection method can determine the performance of the tested radar object simulator, thus solving the problems that the radar object simulator cannot be accurately evaluated when the test signals are too complex.
Description
technical field [0001] The invention belongs to the technical field of radar target simulator calibration, and in particular relates to a radar target simulator calibration system. Background technique [0002] The radar target simulator is specially developed for the test requirements of radar guided missile products. It can simulate and reproduce the echo signal containing radar target and environmental information, and is widely used in the debugging and performance evaluation of radar systems and subsystems. Using the radar target simulation technology can quickly check the main characteristic parameters of the radar system, thereby shortening the development cycle of the radar and reducing the development cost of the radar. [0003] However, the current radar target simulator does not have a complete and systematic calibration method, and can only simply test the parameters related to power and frequency of its output signal. At present, there is no corresponding calib...
