TNO Defensie en Veiligheid (author), Maas, A.P.M. (author), van Vliet, F.E. (author)This paper describes the design and performance of a low-cost synthesized FMCW radar module, operating in S band. The bi-layer PCB contains a frequency-agile low phase-noise synthesizer and three identical coherent receive-channels. The transmit channel has an automatic power control system that reduces the output power when a large reflection...conference paper 2008

TNO Defensie en Veiligheid (author), van Dijk, R. (author), van der Houwen, E.H. (author), Maas, A.P.M. (author)A phased-array FMCW radar has been design and built from COTS components. The generation of the frequency sweep is done by mixing a central local oscillator signal with a baseband sweep of a direct digital synthesizer (DDS). To ensure maximum flexibility the receive side has been equipped with it's own swept signal. The transmit frequency...conference paper 2008
