Abstract
The program BMPAT is a FORTRAN 77 program designed to readily evaluate the amplitude and phase response of general three-dimensional sonar receiving arrays to plane wave arrivals. The program output is directed to two output files, one for amplitude response and the other for phase response, both of which are formatted for plotting using the DREA Surveillance Acoustics Plotting Package. SAPLOT. Features in the program include the ability to handle array elements that have directional response, provision for element amplitude and phase imbalance and for array distortion. The beamforming operation is a linear operation and the steering vectors can either be input directly or can be calculated for phase-to-a-plane beamforming. There are several amplitude window functions resident in the program and additional functions can be input via tables. Beam patterns are sampled in planes which can be arbitrarily oriented relative to the array co-ordinate system. TRUNCATED
