Aircraft Masking Effect on Anti-jamming Techniques

David Machart

Abstract:	The LRBA has established a test procedure to evaluate the impact of aircraft masking effect on anti-jamming per-formances, as far as GPS is concerned. A method with a Mirage III placed in non-anechoic chamber had been de-veloped to avoid GPS perturbations in the open air. The masking coefficient was measured as a function of the angle between the plane and the source of the jamming signal. L1 and L2 frequencies were studied. The results of the conducted tests are presented for a sin-gle antenna (patch), and secondly for an antenna network (CRPA). A exploitation is then made to evaluate the impact of this masking effect on operational scenarios.
