Unified time sequence control and cooperative processing method for radar system

Abstract

The invention discloses a unified time sequence control and cooperative processing method for a radar system. The method includes the following steps that: a radar control system generates time sequence signals in different forms on the basis of a time sequence according to the processing requirements of a transmitting system and a signal processing system and transmits the time sequence signals;the signal processing system extracts and processes received echo signals according to a transmitting time sequence and a receiving time sequence which are transmitted by the control system, so as toeliminate invalid leakage signals; data interception is performed on the received processed echo signals according to system requirement design, and therefore, signals within a coverage range requiredby the system are reserved, and signals outside the coverage range required by the system are removed; and the signals within the coverage range required by the system are synthesized according to different distances. With the method of the invention adopted, the extraction of effective echo signals is ensured, additional resource consumption that does not contribute to system requirements is reduced, and the problem of excessive resource consumption of traditional schemes is solved, and system operation efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the field of radar signal processing, in particular to a radar system unified timing control and cooperative processing method. Background technique [0002] In order to enable the aircraft in the terminal area and on the route to fly safely, effectively and in a planned manner, it is necessary to monitor the flight dynamics of the aircraft on the scene and in the airspace in real time. The existing surveillance methods mainly include primary radar, secondary radar, automatic dependent surveillance and multi-point positioning system, etc., because secondary radar, automatic dependent surveillance and multi-point positioning system are all cooperative surveillance, it is necessary to install corresponding Only equipment can be monitored. In some special cases, such as when the airborne equipment is damaged or shut down artificially, the monitoring function cannot be implemented. Therefore, primary radar, as the main means of mon...

Problems solved by technology

[0006] 1. Large resource consumption: Since the signal processing system and the transmitting and receiving systems do not have unified timing scheduling, the signal processing system needs to be in working state all the time. It is still the received echo signal when the system is receiving, even the signal that exceeds the coverage required by the system) must be processed, resulting in a large consumption of system resources, especially the additional consumption of signals that do not contribute to the system requirements is large, occupying the system resources, put forward higher requirements for the realization of the hardware of the system, and increase the cost of the system to a certain extent;

[0007] 2. Low operating efficiency: Due to the lack of unified planning, the system has been in the parallel interactive operation of transmission, reception, and signal processing for a long time, and there is no time-sharing processing mechanism, which leads to a large consumption of resources and low operating efficiency of the system. In particular, signals that do not contribute to system requirements increase the burden on system operation, take up system operation time, and may cause system errors, resulting in further reduction in system operation efficiency, extended debugging cycle, large human resource consumption, and development costs. improve
