CRM-203 Type Frequency Modulated Continuous Wave (FM CW) Radar
Paper presents description of the principle of work, structure and basic technical parameters of the Maritime Coastal Surveillance Frequency Modulated Continuous Wave (FMCW) Radar CRM-203 type constructed by Telecommunication Research Institute Ltd. in Gdańsk. Results of its tests in real conditions and comparison with pulse ship radars with scanners installed in the same place will be presente...
متن کاملPolarimetric Detection of Buried Objects by Fm-cw Radar
The subsurface radar suffers from strong clutter from surface and severe wave attenuation in the underground. This paper presents a unique countermeasure to these problems using a polarimetric FM-CW radar equipped with equivalent time sensitivity control (STC) technique. We first apply the polarimetric filtering principle to suppress surface clutter, then, use an equivalent STC technique suited...
متن کاملReal-time and full polarimetric FM-CW radar and its application to the classification of targets
The Sinclair scattering matrix plays a decisive role in radar polarimetry. For realization of a real-time and full polarimetric radar, there are sometechnical problems associated with hardware implementations. Since the FM-CWradar system is suitable for short-range sensing applications, we modified an FM-CWradar to a real-time and polarimetric system by adding a PIN diode-switching circuitry fo...
متن کاملSynthetic aperture FM-CW radar applied to the detection of objects buried in snowpack
This paper presents the principle of synthetic aperture frequency modulated continuous wave (FM-CW) radar and demonstrates the detection results of several objects buried in natural snowpack using the radar system. First, the synthetic aperture technique is explained with emphasis placed on showing that the Fourier transformed beat signal obtained by the FM-CW radar is equivalent to one kind of...
