Performance analysis of port-starboard discrimination for towed twin-line array

• The performance of port-starboard discrimination (PSD) for a target detected by a towed twin-line sonar array is presented. The PSD performance is evaluated by a measure referred to as the port-starboard rejection ratio (PSRR), which is defined as the ratio of the output power in the desired signal direction to that in the mirror direction. Analytical expression for the PSRR is derived, in terms of the array separation, signal-to-noise-ratio (SNR), interference-to-noise-ratio (INR), signal-to-interference-ratio (SIR), angular separation and correlation between the desired signal and the interference, array size and finite sample size.
