Research Institution
A new broadband Doppler-sensitive waveform and processing technique for improved multistatic field performance will be validated using real world data from U.S. Navy sea test exercises. The new strategy realizes improved performance for equivalent transmitted acoustic energy by exploiting both low and high bistatic Doppler target detection opportunities with a single waveform. Data collections in increasingly realistic settings, from in-air to fresh water to at-sea, will be analyzed using the coherent multistatic acoustic processor (CMAP) software – the baseline signal and information processing for the multiple U.S. Navy programs – to provide a complete scientific validation of the approach. These analyses will also quantify the improvements realized over conventional techniques, using test designs that facilitate direct comparison of competing ping strategies. The CMAP MATLAB® prototype software will be updated to include the new processing techniques. In the options, the new waveforms will be installed in source sonobuoys and transmitted at sea in U.S. Navy exercises and the CMAP C/C++ software for in-field use will be updated to include the new processing algorithms and will provide data analysis and contact reports for a U.S. Navy exercise.
