BOUNDS FOR AIRCRAFT TRACKING USING A HYDROPHONE ARRAY
Abstract:
Abstract – Cramér-Rao lower bounds (CRLBs) for aircraft track estimates using an array of hydrophones are presented. Tracking using both bearing and Doppler frequency measurements and in a two layer (air-sea) acoustic environment are considered. The CRLBs for both bearing and Doppler frequency estimation are employed in the tracking CRLBs derivation. The CRLBs provide useful theoretic performance limits that capture the problem complexity and are independent of any particular algorithm. The CRLB gives the lower bound on errors of the estimated tracking parameters, such as the aircraft’s location and velocities. The bounds also can be used to investigate how the system performance varies with typical design parameters, such as number of receivers, the operating frequency and the aircraft flight path relative to the array and the SNR of the received signal. Keywords: Cramér-Rao lower bounds, target tracking,nonlinear filter, hydrophone array, bearing and Doppler frequency measurements 1.
