Abstract: An airport surface target detection, classification and tracking system using a network of multilateration (SSR) sensors and W-band radar sensors is used to provide automatic location and tracking information about ground moving aircraft or targets. The information from the distributed sensors are coordinated to provide accurate location and tracking information for coordination of surface traffic and navigation within an airport.

Abstract: A method and system for determining the location of an object. The system may implement a number of sensors at different locations that are positioned to receive a transmitted or reflected signal from the object. Also disclosed is a system and method of calculating object position based upon the time difference of arrival (TDOA) from each sensor, or the relative time difference of arrival (RTDOA).

Abstract: A method and system for location-determination of a mobile comprising of a receiver with a variable processor gain of up to 45.15 dB for detecting signals transmitted from transmitters that at a farther distance as well as from transmitters that are situated in sparsely populated areas. The system also includes a plurality of terrestrially deployed transmitters known as “pseudolites” that broadcast GPS-like signals, and in addition implementing the use of existing, available information from modulated signals, such as phase, amplitude and convolution with pseudorandom codes.
