METHOD AND SYSTEM FOR CONCATENATION OF RADAR PULSES

摘要

A system and method are described for generating waveforms for use in radar and sonar systems. The system includes waveform generation circuitry, a waveform generator and an up-conversion module. The waveform generator generates concatenated pulse waveforms at an IF band. In a given pulse repetition interval (PRI), the concatenated pulse waveforms comprise a first and second pulse types associated with first and second IF frequencies respectively. The up-conversion module up-converts the concatenated pulse waveforms to an RF band to form first and second sets of pulses. In the given PRI, each pulse is up-converted to a different RF frequency, pulses of different lengths are associated with a similar carrier frequency, and at least one pulse from each of the sets of pulses implements frequency diversity.
