COSBA an experimental system for direction finding and signal parameter estimation

Abstract

The experimental direction finder system COSBA ("COnformal Seekerhead Broadband Array") is described in this paper. The system is used for the localization of arriving signals in a frequency region of several GHz. In future the frequency of the arriving signals will be estimated by the methods proposed by Tsui or Zoltowski. To estimate the angles of arrivals, the polarization states and the complex amplitudes of the received signals sequential sampling methods are applied.
