OVERVIEW OF THE WORK ON THE CLASSIFICATION OF SAR SHIP IMAGERY PERFORMED AT DREO Robert Klepko Defence Scientist Defence Research Establishment Ottawa 3701 Carling Avenue Ottawa, Ontario, K1A 0Z4 KEYWORDS: Synthetic Aperture Radar, SAR Images, Ships, Classification, Computer-based tools, Operator- machine interface ABSTRACT The Airborne Radar and Navigation Section at the Defence Research Establishment Ottawa (DREO) has developed an airborne Synthetic Aperture Radar (SAR) that is capable of generating, in real-time, high- resolution radar images of ocean-going ships. The acquired SAR images of ships must be classified as to the type of ship, and this is performed by a Radar Operator. Classification must be done in real-time and with precision. Given that there are an abundance of images, and that these images can be generated at a high rate, it is difficult for a Radar Operator to maintain an accurate classification without the use of some aids. A. set of Operator aids, in the form of a computer-based graphics system, is currently being researched and developed. This system is called the Radar Operator Interactive Classification and Training System (ROICATS). ROICATS is composed of three main components: computer-based tools, operator-machine interface features, and automated target classification algorithms. This paper gives an overview of the work done on each of these three components. RÉSUMÉ La section du radar aéroporté et de la navigation du centre de recherches pour la défense à Ottawa a mis au point un Radar à ouverture synthétique (ROS) qui génére des images radars à haute résolution de navires de haute en temps réel. Un opérateur de radar doit classer les images ROS des vaisseaux en catégories. La classification doit étre faite en temps réel et avec précision. À cause de l'abondance d'images et parce qu'elles sont générées tres vite, l'opérateur du radar peut difficilement les classer correctement sans aide. Nous mettons au point un ensemble d'aides à l'opérateur, sous la forme d'un systéme informatique graphique. Ce systéme est appelé le Systéme d'entrainement et de classification interactive avec l'opérateur radar (SECIOR). Le SECIOR comprend trois composantes: outils informatiques, interface usager et algorithme de classification automatique de cibles. Ce rapport résume le travail accompli pour chacune des trois composantes. 1.0 INTRODUCTION accomplish the main requirement for classification, which is to determine whether a ship is combatant or The Airborne Radar Section at DREO has developed an airborne SAR system, called SPOTlight SAR, which is capable of generating, in real-time, high-resolution radar images of land targets, and ships at sea. This SAR system is actually a new operational mode that will be incorporated into the AN/APS-506 Maritime Search radar on the CP-140. The AN/APS-506 radar, as it exists now, has three conventional modes of operation which are used for: periscope detection; weather watch and navigation; and long range detection of ships. It is possible to track a single target in all three modes. Because of the conventional search radar's coarse spatial resolution, it is not possible to noncombatant. Hence, the SAR mode was introduced to provide both this capability, and a capability for high-resolution land imaging. The SAR mode can be sub-divided into one of three sub-modes. In the first sub-mode, called the SPOTlight mode, the antenna is maintained fixed on a specific target, a certain amount of radar returns are accumulated, and a very high resolution radar image 1s generated from this data. With this image, detected targets can be classified. In an adaptive version of this mode, moving ship targets on the open ocean are tracked and compensated for their motion.
