Abstract :
The paper presents a new practical method for radio direction finding and the processing results of real data collected by the direction finding trial “test-bed”, which was developed at DREO and is based on DBF technology. In the paper, the multipath correlation function from sensor to sensor and multipath spectrum are investigated. The combination of multiple snapshots is used to carry out direction-frequency estimation, which can cope with multipath signals. Real data processing results which illustrate the performance of the practical algorithm are presented
