A multi-base cooperative radio detection system and detection method

Abstract

The invention discloses a multi-base cooperative radio detection system and a detection method. The system transmits FM step signal and communication data to the slave base station through the master base station. Obtain the first clock signal from the communication data from the base station, adjust the local clock signal according to the first clock signal to obtain the second clock signal, determine the first receiving time of the frequency modulation step signal transmitted by the main base station based on the second clock signal, and detect The second receiving time of the reflected FM stepping signal reflected by the target; the first receiving time and the second receiving time are used as detection information, and are sent to the main base station through the Ethernet. The main base station uses the time difference positioning method to determine the location information of the detection target based on the detection information, ensuring the time synchronization of the radio detection devices at multiple points, thereby improving the distance accuracy; improving the multi-pulse accumulation effect of the radio detection devices at multiple base stations, thereby improving detection distance capability.

Description

technical field [0001] Embodiments of the present invention relate to radio detection technology, in particular to a multi-base cooperative radio detection system and detection method. Background technique [0002] The radio detection method is an effective non-cooperative target detection method, and the three-coordinate safety control and regional alert control of the target area can be realized through the radio detection method. [0003] Radio detection means include single-base mode and multi-base mode. Wherein, the monostatic mode may be a radar detection mode. However, since the radar transmits signals at the transmitting end, the receiving end cannot receive the signals, resulting in a large coverage blind area in the single-base mode radio detection method. The radio detection means in the multi-base mode can easily solve the problem of coverage blind spots, but how to synchronize the radio detection devices in multiple places is still an urgent problem to be solv...
