“…The detection of the target’s sound is associated to the estimation of the target’s bearing using multiple hydrophones. How to estimate the bearing of the target sound using multiple hydrophones is discussed in [ 7 , 10 , 11 , 12 , 13 ]. However, this bearing estimation (target detection phase) is not within the scope of our paper.…”

This paper considers locating an underwater target, where many sonobuoys are positioned to measure the bearing of the target’s sound. A sonobuoy has very low bearing accuracy, such as 10 degrees. In practice, we can use multiple heterogeneous sonobuoys, such that the variance of a sensor noise may be different from that of another sensor. In addition, the maximum sensing range of a sensor may be different from that of another sensor. The true target must exist within the sensing range of a sensor if the sensor detects the bearing of the target. In order to estimate the target position based on bearings-only measurements with low accuracy, this paper introduces a novel target localization approach based on multiple Virtual Measurement Sets (VMS). Here, each VMS is derived considering the bearing measurement noise of each sonar sensor. As far as we know, this paper is novel in locating a target’s 2D position based on heterogeneous sonobuoy sensors with low accuracy, considering the maximum sensing range of a sensor. The superiority (considering both time efficiency and location accuracy) of the proposed localization is verified by comparing it with other state-of-the-art localization methods using computer simulations.

Sonobuoy is a sensory device collecting underwater acoustic signals and transmitting them to some base stations via RF waveforms. In this paper, newly developed Turkish sonobuoy project's sea performance is presented. The proposed system architecture has been developed as a prototype in the lab environment. Lab experiments have been conducted successfully over a test bench representing typical submarine detection case. These experiments are designed to calibrate sensory system and optimize the RF transmission. The sonobuoy system has been used in open sea environment for the similar submarine scenario. The bearing angle representing submarine position has been detected within ± 10 o accuracy as required. We, then, compared the lab and experimental open sea results that were identical.
