DDRE s areas of concern include sensor systems and related countermeasures, technologies for target identification and stealth, command and control systems, computer assisted exercises, software engineering, and operations research. Operations Research Department provides modeling and simulation in support of force level assessments and advice to military acquisition components. MRS is a multipurpose experimental radar system designed to perform real time calibrated polarimetric measurements of target cross section and signature. The radar is fully polarimetric, employs a 20 w. CW waveform, capable of being swept in frequency over the band 2 GHz to 18 GHz, and of measuring a 1 sq. The radar achieves high resolution with a phase coded waveform and wide instantaneous bandwidth, thus enabling measurement capability not achievable with synthesized high resolution waveforms.
Complete parameters are available on request.
The radar has been employed by DDRE in a campaign to reduce the RCS of Danish ships, and to evaluate the effectiveness of deployed chaff. Such measurements of dynamic phenomena requires high resolution in both range and time. The system is mounted in a standard shipping container and thus is readily transportable. Among the extant decomposition theories for analyzing polarimetric responses is the so-called Krogager decomposition theory. Krogager has developed a three component decomposition which applies to the coherent case and results in scattering components associated with a sphere, a diplane, and a helix.
