2. Antenna array mapping for DOA estimation in radio signal reconnaissance
Abstract : To counter radio signal reconnaissance, an efficient way of covert communication is to use subsecond duration burst transmissions in the congested HF band. Against this background, the present thesis treats fast direction finding (DF) using antenna arrays with known response only in a few calibration directions. READ MORE
