Abstract

The invention provides an unmanned aerial vehicle-mounted passive bistatic radar device and a target positioning method based on the device. The device comprises a receiving antenna, a receiver and adata acquisition and processing device; the receiving antenna comprises a receiving channel and is used for receiving direct wave radio-frequency reference signals from a non-cooperative radar and target echo radio-frequency signals from a target to be detected, and sending the two paths of radio-frequency signals to the receiver; the receiver is used for processing the two paths of radio-frequency signals to obtain direct wave intermediate-frequency reference signals and target echo intermediate-frequency signals, and sending the two paths of intermediate-frequency signals to the data acquisition and processing device; and the data acquisition and processing device is used for positioning a target according to the two paths of intermediate-frequency signals. The device of the invention does not send signals and only receives signals. The device is light and sensitive, and is very suitable for being carried on an unmanned aerial vehicle,.

Description

technical field [0001] The invention relates to the technical field of passive radar, in particular to an unmanned aerial vehicle-borne passive bistatic radar device and a target positioning method. Background technique [0002] The combination of a new generation of large-scale remote-controlled drones and passive dual-multibase early warning radars based on external radiation sources may meet the needs of future low-cost early warning aircraft systems. The development cost of the unmanned early warning system is more than 10 times lower than that of the manned reconnaissance aircraft with the same function, and the maintenance cost of the unmanned aerial vehicle is even insignificant compared with the manned aircraft. The Global Hawk high-endurance unmanned reconnaissance aircraft already equipped by the U.S. Air Force and the BroadArea Surveillance Marine (BAMS) system being developed by the U.S. Navy are both UAVs that mainly implement SAR functions. From a global persp...
