Optimization of Secondary Surveillance Radar Data Processing

Abstract

Secondary surveillance radar (SSR) performs one of the main functions of information service for consumers of the airspace control system. To improve the quality the SSR information is processed using modern information technology. The use of a consistent procedure for processing surveillance system data, due to the functionally completed stages of processing, made it possible to formalize the data processing procedure. However, this significantly limited, and in some cases excluded, the opportunities for inter-stage optimization of data processing. The SSR data processing structure synthesis and analysis are considered in this paper making it possible to perform a joint optimization of signal processing and primary processing of data, as well as to improve the quality of data processing.

Wideband Microstrip Array Antenna Using Defected Ground and Microstrip Structure for Monopulse Secondary Surveillance Radar Application

“…When the interrogator sends mode A which is modulated with a carrier frequency of 1030 MHz, the transponder on the plane will receive this signal and will be sent back by the transponder (reply signal) in the form of a code signal and modulated with a carrier transponder signal of 1090 MHz, This code signal will be processed in the Video Extractor section and so on displayed on the monitor screen in the form of aircraft identification, as well as if the interrogator sends mode C, the information displayed on the monitor screen is "aircraft altitude". MSSR radar can detect the azimuth (coordinates) of the aircraft, the distance of the aircraft to the MSSR Station, and the speed of the aircraft, in addition to the identification and altitude of the aircraft [7][8][9][10].…”

“…Radio Detection and Ranging, is a navigation tool that can detect objects using a transmit and received signal system. In navigation, radar is used as a [6]- [9] ery important means of preventing collisions at sea, especially in foggy and/or night conditions. Because radar can provide the same information in every condition.…”
