To address the urgent need to improve the ship type discrimination capability in maritime target detection, this article explores synthetic aperture radar (SAR) three-dimensional (3-D) imaging of moving ships, which can provide high robustness and stability of 3-D structural characteristics for ship type discrimination.This paper defines the three-
Many Media Access Control (MAC) protocols for Wireless Sensor Networks (WSN) use varia-tions of the popular copyright Sense Multiple Access (CSMA) protocol due to its here simplicity and its high perfor-mance in low traffic scenarios.However, CSMA does not always represent a good choice for WSNs since typical low power transceivers require a signif
