ABSTRACT:
An adaptive parameter signal processor for continuous wave radar ranging systems which provides non-quantized measurements of range. Means are provided to select a suitable portion of the difference frequency waveform, excluding any phase reversal. The period of the difference frequency is measured using the selected portion of the waveform and is converted to frequency. The frequency is, in turn, converted to range. The system parameters are automatically adjusted in accordance with the difference frequency waveform. Override means are also disclosed for adjusting the system at a faster rate in response to predetermined conditions such as when an abrupt decrease in range occurs.
