Abstract :
The compact broad-band direction-finder is presented in this paper. The bearing features and the operation algorithm of the system using the ldquonull-amplituderdquo technique are described in detail. Based on the results of model experiments the sensitivity and resolving capacity of the direction-finder prototype are evaluated. The problems of bearing more than one SHF sources are discussed.
