Problems solved by technology

For the new broadband microwave two-way time comparison signal, the bandwidth reaches 200MHz or even larger, and the system sampling rate must reach 500MHz or more, which far exceeds the current mainstream hardware's large data volume and complex real-time signal processing capabilities. The current mainstream spread spectrum fast tracking method They are all aimed at narrowband spread spectrum signals below 50MHz, but no effective tracking method has been found for wideband spread spectrum signals
[0003] In view of this, the purpose of the present invention is to provide a wideband microwave signal tracking method and system to solve the problem of wideband microwave signal tracking

Abstract

The invention discloses a broadband microwave signal tracking method, which includes: collecting one point at intervals of N points for high-speed data, collecting M times to generate N extracted signals, performing serial-to-parallel conversion on the N extracted signals, and generating a signal sequence S 1 …S N . S 1 …S N Multiplied with the quadrature carrier signal to generate a down-converted signal; according to S 1 …S N The phase of the three channels of local extraction, leading, immediate and lagging, is generated; the down-converted signal is multiplied by the leading, immediate and lagging three code signals to obtain S 1 …S N The three-way multiplication signal of the three-way multiplication signal is respectively integrated and accumulated. According to the accumulation result, the code loop and the carrier loop phase detection are carried out, and the code phase and carrier frequency are controlled according to the phase detection result, so as to realize the tracking and adjustment of the broadband microwave signal. The code phase and carrier frequency are repeatedly controlled according to the phase detection results to realize stable tracking of broadband microwave signals. The technical scheme of the invention extracts high-speed data into blocks, and processes signals in blocks in parallel, so as to realize stable tracking of broadband signals.

Description

technical field [0001] The invention relates to the field of microwave signal tracking, in particular to a broadband microwave signal tracking method and system. Background technique [0002] The bandwidth of the signal used by the traditional two-way time synchronization system is up to 40MHz. The traditional pseudo-code tracking method can realize the stable tracking of the signal, and the existing hardware processing capacity can also meet the processing requirements. For the new broadband microwave two-way time comparison signal, the bandwidth reaches 200MHz or even larger, and the system sampling rate must reach 500MHz or more, which far exceeds the current mainstream hardware's large data volume and complex real-time signal processing capabilities. The current mainstream spread spectrum fast tracking method They are all aimed at narrowband spread spectrum signals below 50MHz, but no effective tracking method has been found for wideband spread spectrum signals.
