The invention discloses a dual-channel broadband radar target and interference simulation system in the technical field of electronic countermeasures. A bearing platform is a mooring unmanned aerial vehicle device or a ground high tower; the airborne electronic load device is used for simulating and generating target echoes and interference signals flying along a set route; the mooring unmanned aerial vehicle device is used for carrying the airborne electronic load device to move in the horizontal direction and the vertical direction and simulating the arrival direction and the pitching angle of the target. The ground high tower is used for installing an airborne electronic load device so as to simulate and generate radar echo signals of a fixed target or a moving target according to a set track, and equivalently simulate distance information, Doppler information, azimuth angle information and target amplitude variation characteristics of the target; the ground guarantee device is in communication connection with the airborne electronic load device and the mooring unmanned aerial vehicle device and is used for sending a control instruction and receiving analog data. According to the invention, simulation of pitching angle change of a radar echo signal can be solved, and the endurance problem of an unmanned aerial vehicle platform is solved at the same time.
Description
technical field [0001] The invention belongs to the technical field of electronic countermeasures, and in particular relates to a dual-channel broadband radar target and interference simulation system. Background technique [0002] In a typical battlefield environment, while radar is monitoring and detecting air targets, it will also face passive interference such as ground clutter, weather clutter, and chaff, as well as active interference signals released by electronic warfare aircraft. In the existing technology, the ground equipment is limited by the site and needs to be erected on a high tower, which cannot simulate the change of the pitch angle; the conventional UAV platform is limited by the battery capacity (usually 2 hours), and it cannot be used for a long time. Work. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the present invention provides a dual-channel broadband radar target and interference simulation system, whic...
