“…This task means mostly extraction of targets form the radar screen. Another interesting alternative can be shown here for traditionally used pulse radars, which are FMCW radar -particularly good for inland waters and short distances due to their known advantages [22], [23], [24], [25].…”

The paper presents results of the research on problem of radar-AIS data fusion in ECDIS. First the concept of these systems according to IMO is provided, then a set of theoretical information concerning radar tracking and the fusion itself is given and finally numerical research with real data are presented. Two methods of decentralized fusion are examined with the analysis of their parameters. A proposal of calculating covariance matrix for radar and AIS data is given. The research are followed with the conclusions.

This paper presents the results of research on the fusion of tracking radar and an Automatic Identification System (AIS) in an Electronic Chart Display and Information System (ECDIS). First, the concept of these systems according to the International Maritime Organization (IMO) is described, then a set of theoretical information on radar tracking and the fusion method itself is given and finally numerical results with real data are presented. Two methods of fusion, together with their parameters, are examined. A proposal for calculating the covariance matrix for radar and AIS data is also given, and the paper ends with conclusions.

In this paper we present a simple SAR radar demonstrator build using commercially available (COTS) components. For the microwave analog front end, a standard police radar microwave head has been used. The Motorola DSP processor board, equipped with ADC and DAC, has been used for generating of modulating signal and for signal acquisition. The raw radar signal (I and Q components) have been recorded on 2.5" HDD. The signal processing has been performed on standard PC computer after copying the recorded data. The aim of constructing simple and relatively cheap demonstrator was to provide the students the real-life unclassified radar signals and motivate them to test and develop various kinds of SAR and ISAR algorithms, including image formation, motion compensation and autofocusing. The simple microwave frontend hardware has a lot of non-idealities, so for obtaining nice SAR image it was necessary to develop the number of correction algorithms at the calibration stage. The SAR demonstrator have been tested using car as a moving platform. The flight tests with a small airborne platform are planned for the summer.
