A digital processor for FMcw IF-correlator ranging systems which detect small IF signals in periodic interference is described. The processor is based on a high-speed low-resolution 6 to 8 bits AD converter synchronized to the ranging system. The study shows that signals below and above the quantization level can be reliably and linearly processed. The processor is shown to be insensitive to variations in interference waveform amplitude and shape. A digital correlatorcomb-filter is used to eliminate responses from periodic interference. Author
