Problems solved by technology

Compared with the original independent complete set of avionics equipment, the avionics integrated architecture has many channels and large processing delays. The ATCRBS reconstructed based on the avionics integrated architecture has actually consumed a processing delay of 3±0.5 microns. second
When upgrading from ATCRBS to Mode S transponder, because it takes 2 microseconds more waiting time to confirm the existence of P4, it cannot meet the response delay index requirements of conventional mode when reconstructing the function of Mode S transponder based on the existing avionics integrated architecture

Abstract

The invention discloses an S-mode transponder based on avionics integrated architecture reconstruction and a design method thereof. The S-mode transponder responds to and responds to an inquiry sent by a secondary surveillance radar interrogator, including: an integrated antenna, a universal Antenna interface unit, radio frequency switch matrix unit, general reception excitation unit, general signal processing unit, general information processing unit; among them, a discrete line is set between the multi-level switch of the general reception excitation unit and the general signal processing unit; FPGA logic identification P1‑ The P3 pulse pair performs response encoding, generates a response digital intermediate frequency signal, converts it into a low-power radio frequency response signal, and makes it reach the multi-level switch, and judges whether there is a P4 pulse, so that the judgment result reaches the multi-level switch through the discrete line. The invention changes the serial processing mode into a parallel processing mode, saves 2 microseconds of waiting for serial processing, makes it meet the response delay index requirement of the conventional mode, and is low in cost and easy to implement.

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...
