An Ultra-Wideband Pseudo-Noise Radar Family integrated in SiGe:C

Abstract

Random noise radar attracts interest mainly because of its low interference and its camouflaged operation, as well as the relaxed requirements concerning transmitter power. Its challenge for very wideband operation is the impulse compression in order to gain range resolution. The use of pseudo random codes largely defuses this problem while keeping most advantages of random noise radar. Modern semi-conductor technologies permit the implementation of code generators operating at clock-rates up to tens of GHz at reasonable costs. The resulting range resolutions are to be found in the cm- and sub-cm-range. The implementation of our radar core is based on SiGe:C-technology. An overview of the basic system configurations will be given.
