Abstract

A method and system for determining a position of a non-cooperative object using a reflected signal from Secondary Surveillance Radar (SSR) system is disclosed. The method enables the ownship to detect a non-cooperative intruder, an aircraft which does not have a functioning transponder. The position and altitude of the non-cooperative intruder are determined from reflected signals by a phased array antenna or mechanically scanned directional antenna (MSDA) to perform tracking and avoidance of the non-cooperative object. In the case that a phased array antenna or MSDA is not available, a co-altitude assumption is applied to conservatively determine an avoidance area around the non-cooperative object, which defines coordinates to be tracked and avoided by the ownship.
