The effect of the number of noise-only tracks is examined for a combined detection and tracking algorithm. Specifically we find the signal-to-noise ratio (SNR) required to ensure that the track containing the target produces the maximum integrator ou

A standard processor for detecting narrowband signals in noise applies the fast Fourier transform (FFT) to overlapped data blocks, and then sums the squared magnitudes of the bins from successive FFTs. The overlap of the data blocks causes these bins

The Cramer-Rao lower bound is used to assess the potential localization accuracy of a horizontal array observing a narrowband moving target. The narrowband signal received by the array is assumed to have only partial temporal coherence, which is mode

A novel method of target motion analysis (TMA) is presented. In contrast to conventional TMA techniques, which use sequences of bearing and/or frequency estimates as their inputs, the new TMA method works directly with hydrophone data to estimate the

The optimal power law is analyzed using characteristic function techniques. For a signal occupying more than about lambda =0.5 of the integration time, the standard square-law energy detector is close to optimal (among the class of power-law detector

An interpolation beamformer (IBF) may be defined as a line-array beamformer where the output for a given beam is formed from the weighted sum of relatively few Fourier coefficients taken from the (spatial) Fast-Fourier transform of the narrowband dat

It is found that performance loss due to the normalization is small, less than 0.2 dB for an example. The loss due to quantization depends on the number of bits used. For one-bit (two-level) quantization, the loss is approximately 1 dB. This can be r

One of the most widely used underwater acoustic sensors in the world is the DIFAR sonobuoy, which consists of an omni-directional hydrophone and two dipole sensors oriented orthogonally. The directional information provided by the dipoles makes it po
