Fast DOA Estimation Algorithm for Moving Source Based on Time-delay Differences Measurement
Xiaosong Luo · Audio Engineering · 2009
DOA estimation method based on time-delay differences is used widely in the field of passive source location. To meet the real-time demands of some location systems, a fast DOA Estimation algorithm for moving source is presented. In this method, only part of time-delay differences is estimated for the measuring of DOA to reduce the computational complexity. Computer simulation results indicate the new method has less computational cost by contrast with traditional method, and based on the reasonable time-delay differences the DOA estimation results are more accurate.
