Ellen E. Case, Brian D. Rigling · 2008
Thispaperdescribes a low-cost acoustic array designed tolocate andtracksmallunmannedaerial vehicles (UAVs). Thegoalofthisproject wastocreate aninexpensive arraywithdynamically placed microphones thatcoulddetect SC= ound andlocate broadband sources inthefar-field through algorithms forarraycalibration andbeamforming. Experiments performed Li using remote controlled airplanes inanopenfield demonstrated favorable results. I.INTRODUCTION
