Abstract : A frequency-jump burst waveform is a sequence of pulses each having the same complex envelope but a different center frequency. When transmitted and received coherently, such a sequence has a range resolution which corresponds to the total bandwidth of the waveform, which may be much greater than that of the receiver IF and video circuitry. Frequency-jump burst waveforms which consist of linear FM pulses uniformly spaced in time and center frequency are considered. Their resolution and ambiguity properties are derived and certain error sources analyzed. In particular, waveforms which are implementable in TRADEX are proposed and evaluated. (Author)
