A continuous wave radar target simulator comprises a power supply conversion module, a radio frequency control module and a radio frequency module; the radio frequency control module comprises an RS422 communication interface, a single-chip microcomputer system, a DDS signal generation circuit, a simulator signal conditioning circuit and a digital IO output circuit, and the radio frequency module comprises an amplitude modulator and a numerical control attenuator having the same waveband; the power supply conversion module provides power supply resources required by the system, and the radio frequency control module outputs Doppler modulation signals to an amplitude modulator in the radio frequency module according to instructions of an upper computer and outputs numerical control attenuation control signals to a numerical control attenuator in the radio frequency module at the same time. The simulator only needs +27 V power supply, the power supply requirement is single, the communication mode is an RS422 interface circuit, program control is convenient, the whole module adopts a program control mode to realize technical parameter adjustment, a potentiometer does not need to be manually adjusted, the performance is more stable and reliable, the simulator system is concise, the three modules are integrally designed, and miniaturized integrated application is realized.
Description
technical field [0001] The invention belongs to the technical field of radar, in particular to a continuous wave radar target simulator. Background technique [0002] A radar-type air-to-air missile seeker target simulator mainly has two types of sideband modulation and DRFM, both of which can realize the target simulation function of the pulse modulation radar seeker; in a certain miniaturized test equipment, only the The target simulator for testing the seeker function in the continuous wave state adopts the sideband modulation type and the digital radio frequency storage type target simulator, which is large in size and high in cost, and does not meet specific requirements. Contents of the invention [0003] Aiming at the existing deficiencies of the above-mentioned technologies, the present invention provides a continuous wave radar target simulator, which uses a DDS-based method to generate a Doppler modulation signal, and can realize the simulation of the target spee...
