Abstract

The invention discloses an S-mode responder based on avionics integrated architecture reconstruction and a design method thereof. The S-mode responder responds to the inquiry sent by a secondary surveillance radar interrogator and makes a response, and comprises an integrated antenna, a universal antenna interface unit, a radio frequency switch matrix unit, a universal receiving and exciting unit,a universal signal processing unit and a universal information processing unit; a discrete line is arranged between a multi-pole switch of the receiving and exciting unit and the universal signal processing unit; an FPGA logic identifies a P1-P3 pulse pair for performing response encoding, generating a response number intermediate frequency signal, converting the signal into a small power ratio frequency response signal and making the signal reach the multi-pole switch, and it is judged whether or not a P4 pulse exists, so that the judgment result reaches the multi-pole switch through the discrete line. The S-mode responder based on the avionics integrated architecture reconstruction and the design method thereof have the advantages that a serial processing mode is changed into a parallelprocessing mode, 2 microseconds of waiting time of the serial processing is saved, so that the requirements for a normal mode response delay indicator are satisfied, the cost is low, and the implementation is easy.

Description

technical field [0001] The invention relates to the field of air traffic control signal processing, in particular to an S-mode transponder based on avionics integrated architecture reconstruction and a design method thereof. Background technique [0002] Avionics integration refers to the comprehensive and integrated design of avionics equipment with similar or overlapping radio frequency bands, the reuse of front-end antenna resources and radio frequency channel resources as much as possible, and the implementation of digitalization in the intermediate frequency signal stage, which is convenient for back-end signal processing and In information processing, various functions of the original independent complete set of avionics equipment (covering radio communication, navigation, surveillance and identification, etc.) are realized by software. The integration of avionics fully draws on the idea of ​​software-defined radio (SDR), and has the characteristics of integration, min...
