Abstract
A 24 GHz FMCW-radar system is presented using a phase-slope algorithm for increased range determination accuracy. Additionally a fractional-N ramp generator provides a highly linear frequency ramp with nonlinearities below 10¿8. These highly linear frequency ramps make post measurement error correction feasible. Especially analysing the phase-slope of the i.f. signal results in an increased measurement precision compared to the standard spectral centre algo-rithm. Another important aspect of the high performance FMCW-radar system is the design of the microwave circuit.
