This paper presents the concept of using a multisensor radio-frequency (RF) system for the detection and tracking of the ball and players in ball sports. The system will be designed as a supporting system for video based tracking systems. The system will consist of two subsystems using RFID and radar technology to detect the position and velocity parameters of the players and ball in sports such as...
To make decisions, cognitive radar must rely on predictions of its own performance. In the literature, these predictions are usually based on some form of Cramer-Rao lower bound. This approach is scientifically sound, but it also brings a possibility of the cognitive controller overestimating radar performance. It therefore makes sense to back theoretical predictions with careful experiments which...
Recently more attention has been paid to the space debris orbiting the Earth. Until 5 July 2016, the United States Strategic Command tracked a total of 17 729 artificial objects including 1419 operational satellites[1]. Information about the current position of these objects should be taken into consideration while planning space missions. There are various solutions to cope with the problem considered...
This paper focuses on a classification of ISAR low resolution imaging of sea targets (cargo vessels) using the most popular classifiers. First, a method of the raw, passive data collection is described. Second, two feature vectors related to a size of the object (its width and length) are extracted, which then are applied for separating the objects into classes. Finally, the accuracy analysis of different...
