Abstract
A radar system is disclosed for detecting profiles of objects, particularly in a vicinity of a machine work tool. The radar system uses a direct digital synthesiser to generate an intermediate frequency off-set frequency. It also uses an up-converter comprising a quadrature mixer, single-side mixer or complex mixer to add the off-set frequency to the transmitted frequency. It further uses a down-converter in the receive path driven by the off-set frequency as a local oscillator. The radar system enables received information to be transferred to the intermediate frequency. This in turn can be sampled synchronously in such a way as to provide a complex data stream carrying amplitude and phase information. The radar system is implementable with a single transmit channel and a single receive channel.
