Problems solved by technology

However, using the existing data fusion method for millimeter-wave radar intrusion prevention will have the following defects: (1) A single millimeter-wave radar sensor does not have data processing capabilities, it can only provide original radar traces, and cannot perform target detection. Identification and tracking, the information output to the data fusion center includes both targets and false alarms and clutter; (2) The millimeter-wave radar anti-intrusion system monitoring covers moving and stationary targets. The trajectory of the target has significant randomness, and the traditional radar tracking filter has limited effect

Description

Technical field [0001] The invention belongs to the field of radar technology, and particularly relates to the field of data fusion technology for millimeter wave radar anti-intrusion. Background technique [0002] With the development of millimeter-wave radar technology, using the high-resolution characteristics of millimeter-wave detection, millimeter-wave anti-intrusion is applied to many fields such as low-altitude detection, collision avoidance warning, and foreign object detection. Because the detection power of millimeter-wave radar is small and the scope of the field that can be monitored is limited, if a large area of ​​scene monitoring is to be realized, it is necessary to coordinate detection by radar sensors distributed in multiple locations, and coordinated detection also requires a data fusion method. The radar points detected by the radar sensors are transformed into the security situation of the surveillance scene. For example, the patent application 201610347672...
