Problems solved by technology

Due to the non-cooperative, uncontrollable, and unpredictable characteristics of external radiation sources, the detection performance of external radiation source radars is greatly limited, resulting in significantly lower detection accuracy of external radiation source radars than traditional radars.
Therefore, in the project, multiple radiation sources, comprehensive utilization of multiple receiving stations, and fusion of multi-station processing results can be used to complete target detection more effectively and improve positioning accuracy, but at the same time, problems such as large amount of calculation and complex processing will occur.
[0004] At present, the signal processing algorithm of the passive radar system is mainly processed by developing a special signal processing board, so the data transmission between the signal processing result and the terminal interface is mainly realized through the serial communication mechanism, and the data transmission is in the unit of "bit". The speed is slow, and the transmission mode is one-way, that is, the signal processing board can only transmit the processing results to the terminal, and the modification of various parameters can only interrupt the processing flow and enter the source code, which is more troublesome to operate , the process of finding modifications wastes a lot of resources
In addition, the traditional terminal interface only has the display function, does not have the real-time monitoring function, and cannot meet the convenient and humanized functional requirements

Embodiment Construction

[0026] The content and effects of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] refer to figure 1 , the external radiation source radar processing system applied in the present invention is mainly composed of an eight-element antenna, a data collector, a digital channelized receiver, a signal processor and a terminal monitoring-display interface. Among them, the eight-element antenna receives FM broadcast signals. The received FM broadcast signals mainly include target signals, direct wave signals, ground clutter and multipath clutter signals. These signals are received by digital channel receivers, channel equalization and downlink After frequency conversion processing, it is converted into original data, and these original data are transmitted to the signal processor. The signal processor performs adaptive clutter cancellation, range-Doppler Two-dimensional correlation calculation, constant false alarm detect...

Abstract

The invention discloses a transmission control protocol (TCP)-based full-duplex communication external radiation source radar data transmission display and control method, and mainly solves the problems that the data transmission speed of the communication between a signal processing board and a terminal interface of the conventional radar system is low, the transmission mode is unidirectional, the modification operation is complex, and the terminal interface function is single. The method comprises the following implementation processes of: setting or modifying signal processing relevant parameters on a monitoring interface, and transmitting the signal processing relevant parameters to a front-end radar signal processing machine through the TCP; performing various types of signal processing on the signal processing relevant parameters by using the signal processing machine, packaging the processing result of the signal processing machine, and transmitting the processing result to a display interface through the TCP; and performing radar data processing by using the display interface after receiving the signal processing data, and finally displaying a target track. The method has the advantages of high data transmission speed, high operability, diversified functions, and high system utilization rate; the processing of the overall radar system can be monitored in real time; and a final track result is displayed.

Description

technical field [0001] The invention belongs to the technical field of radar, and specifically relates to a real-time full-duplex communication based on network Socket-TCP protocol, a method for realizing a monitoring-display interface of an external radiation source radar terminal, which can be used for setting parameters and displaying target tracks. technical background [0002] Conventional active radars are vulnerable to electronic jamming and anti-radiation missiles because their transmitted signals are easily intercepted and intercepted by the enemy. In recent years, passive radar detection technology using radio, television, satellite and other civilian sources of radiation has attracted more and more attention. The passive radar system itself does not need to transmit signals, but uses the existing electromagnetic wave signals in the environment or the target itself for target detection and positioning, so it has anti-jamming, anti-anti-radiation missile, anti-low-a...
