From a high-resolution LFM-CW shipborne radar to an airport surface detection equipment

This paper presents a modification of a linear frequency modulation-continuous waveform shipborne surveillance radar (Perez et al. (2002)) with two antennas to transform it into airport surface detection equipment with a single antenna. The most important additional subsystem for this new equipment is a reflected power canceller to overcome the problem of insufficient isolation between the transmitter and receiver due to imperfect matching between the transmitter and the antenna. This system is currently being developed by the Spanish company Indra Sistemas SA in co-operation with the Technical University of Madrid.
