High-speed scan method used for digital monitoring receiver

Abstract

The invention provides a high-speed scan method used for a digital monitoring receiver, which adopts a continuous tracking and scanning method and a fast Fourier transform method with large space frequency hopping and is capable of implementing dual-mode high-speed scanning. Before scanning, a system carries out estimation of scanning time through user setting and selects an optimal scan mode; an interrupt mechanism and a highly-efficient mode of storing / taking a ping pong are introduced in inner data storage and interaction processes, so that continuous data storage and transmission can be implemented. By adopting the highly-efficient scan mode and the data processing manner, the expenditure of the scanning time is saved, and the scanning search efficiency is greatly improved. The high-speed scan method has the advantages of economy, high efficiency and the like, and is very suitable for economical monitoring receivers or systems.

Description

technical field [0001] The invention relates to the fields of radio monitoring and wireless communication, in particular to a high-speed scanning method for a multifunctional digital monitoring receiver. Background technique [0002] With the development of wireless communication technology, there are more and more management and monitoring problems caused by wireless communication. For example, the radio management department needs to monitor and monitor the reasonable use of spectrum resources, and the security protection department needs to judge and eliminate interference sources and illegal transmitters. All of these need to use the monitoring receiver to scan the signals in the communication frequency band and judge and deal with abnormal frequency points. However, for the monitoring of some broadband signals and burst signals, ordinary receivers have the problems of low scanning efficiency and the difficulty of capturing burst signals. It is necessary to use high-spe...
