Problems solved by technology

[0003] In 2006 and 2007, when aircraft was used to identify the accuracy of ground radar, in the vicinity of Hangjie (the radar pointing is perpendicular to the aircraft track, that is, the relative distance is the smallest), due to the saturation of the transponder, the radar tracking was abnormal, and all the data near Hangjie were Unable to process data, which has a great impact on radar accuracy inspection

Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] The invention relates to a method for realizing a gain controller of a pulse transponder. The function is to realize the automatic adjustment of the uplink and downlink signal strength of the transponder by collecting aircraft position information, and ensure the radar accuracy appraisal effect. The specific process is as follows:

[0029] The first step is to design the hardware control circuit to realize the shunt adjustment of the uplink and downlink signals

[0030] The pulse transponder uses a common antenna for transmitting and receiving, and there is only one radio frequency port. Since the receiving sensitivity of the transponder is different from that of the ground radar, that is, the strength of the uplink and downlink signals is not equal, and the optimal control effect must be achieved by branching control. System block diagr...

Abstract

The invention relates to a pulse responder gain controller implementation method, and the method achieves the automatic adjustment of the intensity of uplink and downlink signals of a responder through collecting the position information of an airplane. The method comprises the following steps: 1, designing a hardware control circuit, and achieving the separated adjustment of the uplink and downlink signals; 2, collecting the position information, and achieving the dynamic adjustment from position to attenuation. The method is used for the automatic adjustment of the intensity of uplink and downlink signals of the responder in a task according to the position of the airplane, is lower in cost and software development difficulty, and is great in application value.

Description

technical field [0001] The invention relates to a method for realizing a gain controller of an impulse transponder. It belongs to the technical field of control engineering. Background technique [0002] The task of the pulse transponder is to be installed on various types of space operating carriers, to work together with ground radars, to increase the range of action, to complete the real-time measurement of the carrier's flight trajectory, to provide high-precision distance and speed information, and to provide information for post-event analysis. ballistic data. The basic principle is to receive the uplink signal of the ground radar and forward it with a delay. The ground radar can measure the radial distance by measuring the time delay, and at the same time track and measure the angle to realize the positioning of the aircraft. During the task, it is installed on the aircraft, the aircraft flies according to the predetermined trajectory, and the ground measurement and...
