The invention discloses a composite high precision radio frequency simulation system based on microwave and millimeter wave. The composite high precision radio frequency simulation system based on microwave and millimeter wave is characterized in that seeker equipment is the user of the radio frequency simulation system; a target signal simulator is used for generation and modulation of a target echo signal; an array feed subsystem simulates an electric wave arrival angle, relative to the tested seeker, of a radiation signal; a computer control subsystem implements command control of the target signal simulator, the array feed subsystem, a three-axle table subsystem and the seeker equipment through fibers or network cables; the three-axle table subsystem simulates the missile motion attitude; and a calibration device subsystem implements calibration of the array feed subsystem. The composite high precision radio frequency simulation system based on microwave and millimeter wave is usedfor a microwave and millimeter wave handover test for the seeker equipment. The composite high precision radio frequency simulation system based on microwave and millimeter wave analyzes the angularposition error source, can eliminate or correct the error from the source, and can improve the target angular position accuracy of the composite radio frequency simulation system based on microwave and millimeter wave.

Description

technical field [0001] The invention relates to a high-precision radio frequency simulation system based on the combination of microwave and millimeter wave, and belongs to the technical field of radio frequency simulation systems. Background technique [0002] The extensive use of precision-guided weapons in modern warfare and the results they have achieved have shown that it plays a pivotal role in modern warfare. In the future, there will be fierce competition among various high-tech precision-guided weapons on the battlefield. The strike accuracy of precision-guided weapons mainly depends on the guidance technology of the seeker. For target detection in the background of strong ground clutter, more millimeter-wave seekers are used to meet the needs of high-precision detection and imaging. [0003] The radio frequency simulation system can realize the semi-physical simulation of the precise guidance and control system of the weapon system, as well as the performance test ...
