Operational safety will become of a prime concern, as many of UAS would fly close to residential areas. This paper is devoted to small UAS (sUAS) collision risk with static ground objects in populated zones. Solutions of sense and avoid problem involve the use of a passive localization method to detect collision threats. This method uses the acoustic signature of the UAS. The method is based on resampling of received signals of moving UAS for Doppler shift compensation, evaluation of generalized cross-correlation with phase transforms and signal delays grouping using cyclic sums and products.
