Abstract :
The holographic array processing (HAP) algorithm calibrates the integrated effect of the medium between a reference (virtual) array, near the source, and the receiving array. The effect of truncating both the receiving and virtual arrays on the performance of the HAP algorithm is investigated. Simulation for a horizontally stratified, range dependent ocean is performed using a higher order PE (parabolic equation) code. It is shown that the holographic array processing algorithm is more sensitive to the length of the virtual array than to the length of the receiving array
