A study of direction finding method for passive airport surveillance radar

Abstract

The current Air Traffic Management (ATM) uses various radio equipment. The radar is the one of important system and the recent ATM uses a combination of several radar systems. However, the conventional Primary Surveillance Radar have a high cost of maintenance and operation. Recently, Multi-Static Primary Surveillance Radar (MSPSR) has attracted interest from the civil aviation research field. The MSPSR is classified into passive bistatic radar (PBR).In this paper, we discussed receiver side direction finding method (DF) for the passive PSR system. This method is required for MSPSR. We show the DF method based on interferometer and experimental results, and we discussed the potential of DF for the passive PSR system.

The effect of far-field cylindrical scatterers on radio direction finding and beamforming estimated by cylindrical array of dipoles

“…The interest in smart antennas for airplane and aerospace applications such as localization, tracking, navigation and surveillance systems is growing increasingly [1]. For this purpose, the radio direction finding and the beamforming methods were studied to improve the capabilities of antenna arrays in different airplane and airport services [2][3][4]. In a more realistic situation such as airports, the effects of the scatterer in the presence of the mutual coupling between the antenna elements are not negligible and it should be considered in the corresponding models [5].…”
