Multi-base coordinated radio detection system and detection method

Abstract

The invention discloses a multi-base coordinated radio detection system and a multi-base coordinated radio detection method. The multi-base coordinated radio detection system transmits a frequency-modulation stepping signal and communication data to a slave base station by means of a master base station; the slave base station obtains a first clock signal from the communication data, and adjusts alocal clock signal according to the first clock signal to obtain a second clock signal, determines first receipt time of the frequency-modulation stepping signal transmitted from the master base station based on the second clock signal, and determines second receipt time of a reflected frequency-modulation stepping signal reflected by means of a detection target; and the first receipt time and the second receipt time are regarded as detection information and transmitted to the master station by means of an Ethernet. The master base station determines position information of the detection target based on the detection information by adopting a time difference positioning method, and ensures the time synchronization of radio detection devices at a plurality of points, thereby improving thedistance precision, improving the multi-pulse accumulation effect of the radio detection devices of multiple base stations, and further enhancing the distance detection ability.

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...
