ABSTRACT:
A process that derives estimates of range and range-rate during the radar ack of an object, when the radar employes a linear frequency modulated waveform. FM waveforms at the radar wavelength are transmitted. The frequency of the radar echos are measured and the difference between the incoming frequency of radar echos and the local oscillator frequency is estimated. The signal is decomposed into Range and Range rate. Implementation of the decomposition device can either be a sequence of stored software or a hardwired processor.
