Abstract

The invention belongs to the technical field of radar and discloses a method for detecting multi-station radar signal fusion based on Neyman-Pearson rule digitalizing. The method comprises the following steps: arranging a multi-station radar system, including a signal fusion detection center and N radar stations; confirming a digitalizing bit b for a received echo signal by each radar station, thereby acquiring the quantity of digitalizing zones: M=2b; giving a false alarm probability of the signal fusion detection center and confirming the digital thresholds of the N radar stations; digitalizing the echo signal by the N radar stations according to the respective digital thresholds and transmitting a corresponding mark after the digitalizing to the signal fusion detection center; detecting a target by the signal fusion detection center according to the false alarm probability and the corresponding mark after the digitalizing for the echo signal by the N radar stations; and reducing the communication bandwidth required when the radar station echo signal is transmitted to the signal fusion detection center.

Description

technical field [0001] The invention relates to the field of radar technology, in particular to a multi-station radar signal fusion detection method based on Neyman-Pearson (Neyman-Pearson) criterion quantification, which can be used to reduce the distance between radar and signal fusion center in multi-station radar signal fusion detection. communication bandwidth. Background technique [0002] A multi-station radar network consists of a signal fusion center and multiple radar stations. Compared with single radar, multi-station radar network has the advantages of larger detection range, higher positioning accuracy, stronger survivability and stronger anti-jamming ability. Therefore, the research of multi-station radar network has become a new research hotspot. In the research of multi-station radar network, the signal fusion detection method of multi-station radar is an important research direction. [0003] According to the existing research, the signal fusion detection...
