Problems solved by technology

[0002] Currently, with the application of vehicle-mounted mobile radio signal monitoring and direction-finding equipment (hereinafter referred to as the monitoring vehicle), there are application scenarios where the operator performs signal search while driving the monitoring vehicle. In addition to the driver of the monitoring vehicle, it is necessary to have a special person to observe the monitoring and direction-finding parameters in order to approach and search the signal, find the signal transmitter, and occupy human resources; and if a single person performs the signal approach detection and search work of the monitoring vehicle , the driver is required to drive the monitoring car while observing the monitoring data on the display screen, which has potential safety hazards

Embodiment 1

[0043] This embodiment relates to a radio signal monitoring and direction-finding method based on auditory mapping. The method is applied to the vehicle-mounted mobile radio signal monitoring and direction-finding equipment (hereinafter referred to as the monitoring vehicle), so that the driver can search for the target signal while driving the monitoring vehicle. In the application scenario, the driver can independently complete the radio signal approach detection and search work of the monitoring car under the condition of safe driving, which improves driving safety and search efficiency.

[0044] Such as figure 1As shown, a radio signal monitoring and direction finding method based on auditory mapping, the method includes: generating a virtual sound source signal with an angle attribute according to the monitored radio signal received by the antenna.

[0045] Preferably, in this embodiment, the monitored radio signal is a radio frequency signal, and performing virtual sound...

Abstract

The invention discloses a radio signal monitoring and direction finding method based on auditory mapping and a processor and belongs to the technical field of radio monitoring. The method comprises astep of generating a virtual sound source signal with an angle attribute according to a received monitored radio signal, wherein the monitored radio signal is a radio frequency signal, and the virtualsound source mapping processing with an angular attribute on the radio frequency signal includes a spectrum mapping mode and a directionality mapping mode, in the spectrum mapping mode, the virtual sound source mapping processing with the angular attribute on the radio frequency signal does not need to perform direction finding processing on a radio frequency signal, and in the directionality mode, the virtual sound source mapping processing with the angular attribute on the radio frequency signal needs to perform direction finding processing on the radio frequency signal. The processor performs all the steps of the above method when executing computer instructions. According to the invention, the signal sensing and the close detecting and finding work of a monitoring vehicle can be separately completed at the same time when a driver monitors the safe driving of the vehicle, and the driving safety and the searching efficiency are improved.
