The feasibility of accomplishing high frequency direction finding against short duration (100-1000 ms) HF skywave signals using narrow aperture antennas is investigated. Two statistical procedures for estimating the signal bearing are proposed and compared. These procedures employ time averaging to reduce the large instantaneous bearing error caused by the phase and amplitude distortion of the wavefront due to scattering and multipath interference. Results are presented using data collected with the Southwest Research Institute Coaxial Spaced Loop HFDF system. It is shown that for a limited sample of data from this system the standard deviation of the bearing estimate for a 200 ms signal varied from 15 to 59 degrees. (Author).

The use of spread-spectrum signals has increased dramatically in military radio communications. This report locates methods for direction-finding direct-sequence spread-spectrum (DS/SS) signals; digital methods are of special interest. A literature survey was conducted to see if there are any known methods. Investigated if a DS/SS detection method using a square-law detector can be extended to direction-finding. By use of computer simulations, show the performance of the methods found. Benefits and problems are also discussed.
