Multilateration (MLAT) is an increasingly important location and identification system for surface traffic surveillance, is in use in large airports such as London-Heathrow, Frankfurt/Main and Rome-Fiumicino. Target location can be extended to approach and terminal area surveillance (wide area multilateration, WAM), with a system coverage to some hundred kilometers around the airport. Practically...
Location and identification of cooperating aircraft in the airport area (and beyond) may be implemented by multilateration (MLAT) systems using the secondary surveillance radar (SSR) mode S signals. Most of these signals, spontaneously emitted from on-board mode S transponders at a fixed carrier frequency, arrive randomly at the receiving station, as well as many mode A/C replies from legacy transponders...
Traditional millimeter wave Surface Movement Radar (SMR) have been designed and tested. A novel concept for the design of a new SMR is suggested based upon Synthetic Aperture Antenna and Noise Radar Technology. It enables designing of SMR without mechanical rotation of an antenna, but applying several nonmoving Synthetic Aperture Antennas instead. Application of Noise Radar Technology is also considered...
The "multilateration" (MLAT) system is a surveillance and identification element of the A-SMGCS using the SSR transponder (Mode S or even A/C) reply/squitter as signals received by fixed stations where the time-of-arrival (TOA) is measured. In a central processing unit, the target position is estimated by the TDOA technique (time difference of arrival), for which a station is assumed to...
This paper is focused on the implementation of an innovative vehicles surveillance system using the 1090 MHz channel. SSR (secondary surveillance radar) mode S (selective) exploitation in high traffic environment calls for enhancing communication capacity. In the multilateration and ADS-B applications, the presence of both SSR mode S replies and squitter makes the superimposition of 1090 MHz signals...
