Title:
INTERFERENCE LISTENING METHOD AND DEVICE, AND RADAR
Document Type and Number:
WIPO Patent Application WO/2022/166241
Kind Code:
A1
Abstract:
The present application relates to radar technology, and in particular, to an interference listening method and device, and a radar. Working periods of the radar to which the method is applied comprise at least one full detection period and at least one detection while listening period, the full detection period comprises a plurality of transmission cycles, and the detection while listening period comprises at least one transmission cycle and at least one listening cycle. The method comprises: when the radar is within the transmission cycle, the radar generates and transmits a first detection signal, and receives an echo signal corresponding to the first detection signal, so as to perform target object detection; and when the radar is within the listening cycle, the radar generates but does not transmit a second detection signal, and acquires an electromagnetic signal that can be detected by the radar in the listening cycle, so as to perform interference listening. Therefore, performing target detection and listening at a same detection frame is realized.
