Abstract

A microwave ranging system which employs a composite FMCW/CW measurement technique is described. An FMCW radar is used to find the approximate range of the target. The FMCW radar returns are processed in the spatial domain using the Fast Fourier Transform (FFT). In order to provide higher resolution, without an excessive increase in processing time, a modified “picket fence” algorithm is employed. A comparison of experimental results obtained from alternative resolution enhancement techniques is also included. A precision CW distance measurement is able to be resolved on the basis of the FMCW result to provide an accurate sub-millimetre range solution. A microcontroller based X-band prototype system suitable for industrial applications is described
