Trial Results on Bistatic Passive Radar Using Non-Cooperative Pulse Radar as Illuminator of Opportunity

The paper presents the concept of passive radar exploiting the active Air Traffic Control (ATC) radar as the source of illumination, and the primary results of the measurement campaign carried out at the DSP Laboratory of the Warsaw University of Technology. The system, built using commercial off the shelf components, was able to detect and track airliners landing at Warsaw airport. To verify the system accuracy the IFF mode S messages were recorded, providing ground truth of the observed planes.

Radar and Optical Images Fusion Using Stripmap SAR Data with Multilook Processing

The paper presents the real-life data results of SAR and optical images data fusion. The fusion has been carried out for SAR images obtained in stripmap SAR mode using multilook processing with different methods of final image creation. The aim of the fusion was to enhance the target recognition capabilities on the Earth surface for a simple single-channel SAR receiver.

The paper presents new high resolution SAR results of real-life measurements using an updated ARS-400/ARS-800 SAR sensor installed on the maritime patrol aircraft M-28. The main role for such radars is surveying the sea surface, and the imaging of selected targets (e.g. ships, roads, vehicles, buildings, etc.) to help the operator in classifying them. In the present day increasing computing power, improved algorithms and general technological progress has allowed the obtaining of better results in SAR imagery.

The work is devoted to fusion of radar and radiometer images. Noise waveform SAR generates radar images of reflective objects of its field of view. A bistatic radiometer with synthetic aperture estimates the thermal radio emissions of the objects along their angular coordinates and even range. The estimated brightness temperatures of rough and smooth surfaces are different, as well as the radar responses from them. Identification of the parameters of objects surfaces may be done using results of joint processing of images generated by both sensors. The optimum and quasi-optimum criteria for fusion of the images were obtained. The latter was experimentally checked. It approves the opportunity to fuse the images for further estimation of some parameters of objects surfaces. The results obtained may be used in environmental and security applications.
