Zusammenfassung: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 itpsilas own swept signal. The transmit frequency generation and receive frequency generation are derived from the same local oscillator signal and clock to ensure coherent operation. This architecture makes a very flexible platform as the waveforms can be changed, transmit and receive and be independently programmed and the system is scalable, also by the mechanical outline of the system and antenna.
