Abstract
Official abstract text for this publication.
A Doppler radar system that avoids blind ranges, range ambiguities, blind speed and/or Doppler ambiguities. Pulse width, repetition interval and pulse type are varied from pulse to pulse within a coherent processing interval.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of determining range information for a target comprising: generating a pulse signal comprising a train of transmit pulses, the transmit pulses having a pulse width, pulse waveform, and pulse repetition interval (PRI), at least two of which are each different for at least two consecutive pulses within the train of transmit pulses for a given Coherent Processing Interval (CPI), with the CPI defined by a set of transmit pulses in the train having a det…
