Picture Compilation in Multi-Platform Sensor Networks

The traditional approach to maritime operations in open ocean conditions (‘blue waters’) is platform centric. In this approach, an environmental picture is generated on each platform separately. High quality tracks can be made available to other platforms through classic data links, e.g. Link 11 and 16. In case of maritime operations in littoral...

Adaptive state multiple-hypothesis tracking

In tracking algorithms where measurements from various sensors are combined the track state representation is usually dependent on the type of sensor information that is received. When a multi-hypothesis tracking algorithm is used the probabilities of the different hypotheses containing tracks in different representations need to be re-evaluated...

Application of the M6T Tracker to Simulated and Experimental Multistatic Sonar Data

This paper describes the first results of applying a multi-sensor multi-hypothesis tracker, called M6T, to simulated and experimental sonar data sets. The simulated data have been generated in the context of the Multistatic Tracking Working Group (MSTWG). For a number of cases (number of sensors and number of input false contacts) we evaluate a...

Multi-sensor fusion using an adaptive multi-hypothesis tracking algorithm

The purpose of a tracking algorithm is to associate data measured by one or more (moving) sensors to moving objects in the environment. The state of these objects that can be estimated with the tracking process depends on the type of data that is provided by these sensors. It is discussed how the tracking algorithm can adapt itself, depending on...

Maritime target and sea clutter measurements with a coherent Doppler polarimetric surveillance radar

Doppler polarimetry in a surveillance radar for the maritime surface picture is considered. This radar must be able to detect low-RCS targets in littoral environments. Measurements on such targets have been conducted with a coherent polarimetric measurement radar in March 2001 and preliminary results from that campaign are presented. The system...

An overview is given of subjects that are relevant for the system's design, Discussed are: physical phenomena that can be exploited by a coherent polarimetric radar, the effecs of...

Fusion of Radar and EO-sensors for Surveillance

Fusion of radar and EO-sensors is investigated for the purpose of surveillance in littoral waters is. All sensors are considered to be co-located with respect to the distance, typically 1 to 10 km, of the area under surveillance. The sensor suite is a coherent polarimetric radar in combination with a set of camera's sensitive to visible light,...

The FRESNEL Program: Fusion of Radar and Electro-optical Signals for Surveillance on Land

Area surveillance for guarding and intruder detection with a combined camera radar sensor is considered. This specific sensor combination is attractive since complementary information is provided by the respective elements. Thus, a more complete description of objects of interest can be obtained. Several strategies to fuse the data are discussed...

Fusion of Radar and EO-sensors for Surveillance

Fusion of radar and EO-sensors for the purpose of surveillance is investigated. All sensors are considered to be co-located with respect to the distance of the area under surveillance. More specifically, the applicability for such multi-sensor systems is examined for surveillance in littoral watters. The sensor suile is a coherent polarimetric...

On measures of Performance to Assess Sensor Fusion Effectiveness

In this paper measures of performance (MOP's) are discussed with which the efectiveness of sensor fusion can be assessed. A series of objectíve measures are outlined to characterize efectiveness of the detection, tracking and classitication processes. The applìcabílity of several MOP's is demonstrated for an example in which radar and camera...
