Problems solved by technology

It is necessary to exchange information with the radar, and exchange attribute information with the target to be identified. In the case of a large number of platforms and a variety of types, the inquiry and response signals are complex and intertwined, which is prone to confusion
The cooperative work system also brings many uncertainties to the system, such as whether the cooperative equipment is turned on, whether it is working normally, whether it is occupied, etc., the identification of friend or foe can only identify our side, and cannot uniquely confirm the enemy's shortcomings. ATC mode collaborative IFF comprehensive identification method, can better provide the overall situation, enemy, our side and neutral party information
Secondary Surveillance Radar (SSR) is a commonly used means of flight dynamic surveillance. However, SSR air traffic control has many limitations, such as multipath reflection, asynchronous interference and overlap of response signal pulses, etc., which lead to the A , In the C working mode, the monitoring target appears to be false and lost
On the existing surveillance system, SSR air traffic control and IFF are independent systems. SSR air traffic control is mainly used in air traffic control, and IFF is mainly used in battlefield identification. IFF needs a radar cooperation to record the track of the existing SSR air traffic control. It mainly deals with targets in A and C modes, and mainly processes mode 4 for IFF interrogation mode. These traditional modes are susceptible to interference and reflection, and it is difficult to eliminate false targets even through track processing.

Embodiment Construction

[0018] refer to figure 1 . According to the present invention, the SSR air traffic control track and the IFF track are fused according to the following steps: in the SSR air traffic control and IFF integrated system,

[0019] S1: Mode A and C are merged, with the A mode target position of the SSR air traffic control as the center, and the time threshold and position threshold are set according to the antenna scanning beam width and detection error level, and the C of the SSR air traffic control that falls within the threshold Mode target and A mode target dots are merged, and the obtained AC merged target dots and S mode target dot position data are judged by the target mode address code and position. The m / n logic judgment method is used to make association judgments on attributes with the same pattern code or non-contradictory attributes, and perform AC mode combined target, S mode target and ACS mode target track for the set of point traces that have m times of successful a...

Abstract

The invention discloses a method of carrying out fusion processing on SSR navigation management and IFF multi-mode cooperation track. A clear and reliable air monitoring graph can be supported to generate and civil air and an out target monitoring and identification capability can be increased. A technical scheme is characterized by in a secondary monitoring radar SSR navigation management and identification friend or foe recognizer integration system, firstly, carrying out trace point merging and track starting on data of A, C and S general calling mode targets of an SSR navigation management mode; secondly, carrying out prediction and roll-call inquiry on an S general calling mode track so that the SSR navigation management acquires a roll-call track of the S mode; according to a target point track angle, calculating a belonging area number, carrying out relation determination on SSR navigation management target tracks in the same area and an adjacent area and generating a target track after the SSR navigation management and the IFF are fused; and then associating and fusing attributes and positions of target data under different IFF guiding modes and the target tracks of the AC and S modes of the SSR navigation management and forming an SSR navigation management and IFF fusion target track so that continuous monitoring and identification to an air target are realized.

Description

technical field [0001] The invention belongs to the method for secondary surveillance radar SSR air traffic control data processing and IFF (IFF) cooperative monitoring and target recognition in the field of cooperative sensor target recognition. Background technique [0002] In the existing technology, in order to continuously and stably track and interrogate the air passenger aircraft, improve the air control environment, and improve the control efficiency, it is generally possible to realize the real-time monitoring of the air passenger aircraft through the reasonable division of the secondary radar data processing function modules of the air traffic control and the use of filter tracking technology , and maintain normal communication with it. Each flight has a corresponding flight plan; civil aviation aircraft should not deviate from the scheduled route; our aircraft are flying according to the flight plan. If it can be related to the flight plan, it can be preliminaril...
