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...
Multilateration systems based on secondary surveillance radar (SSR) systems and omnidirectional antennae are operational today (Bezousek, 1998 and Galat, 2004). Assuming the replacement of the single-element antenna by an array, we proposed new algorithms to discriminate overlapped signals in previous works (Petrochilos et al., 2002, 2004 and 2007); other solutions were also proposed in the literature...
Multilateration systems based on secondary surveillance radar (SSR) and omni-directional antennae are operational today (P. Bezousek, 1998) with expected capacity limitations due to the increase of the air traffic. Assuming the replacement of the omni-directional antenna by an array, we proposed new algorithms in previous works (N. Petrochilos, July 2002), (N. Petrochilos, et al., May 2004). Unfortunately,...
