Abstract
An optimal design of preamplifiers is proposed for broadband (BB) passive sonars, in which the frequency response function (FRF) of a preamplifier is optimized to maximize the output signal-to-noise ratio (SNR) of BB passive processing. The optimal design depends on passive source signals, background noise and array shapes. It contrasts with the conventional design where preamplifiers are used for whitening or conditioning hydrophone signals due to historical reasons. A hull-mounted 2-D virtual array is used as an example to show the advantage of the proposed optimal design.
