Abstract:

Propagation Research Associates, Inc., teamed with Ultra Electronics UnderSea Sensor Systems Inc., with support from Boeing Integrated Defense Systems proposes to design and assess the performance of a Sonobuoy Location System (SLS) that implements the latest digital synchronization technology to align uplink and downlink signals. Current digital synchronizer technology will allow the PRA SLS to detect and measure low Doppler signatures that will be expected from the relative velocities between the patrol aircraft and the deployed sonobuoys. This digital technology will allow PRA to modify waveforms to adapt system performance based on operational sensitivity requirements. PRA will design and evaluate two SLS concepts - one that uses a two-way downlink/uplink and a combination of range/Doppler measurements made on the aircraft, and another that uses a one-way downlink and a combination of time-difference-of-arrival/frequency-difference-of-arrival measurements made on the sonobuoy and communicated to the patrol aircraft on existing communication channels. The objectives of this effort are to achieve required sonobuoy track accuracies while operating at any altitude, utilize as much of the existing SLS hardware and infrastructure as possible, minimize the impact of new hardware on the existing system, mitigate the effect of radio frequency interference and 5) maintain a cost effective solution.
