Abstract :
We propose a DFT based pulse Doppler processing receiver for staggered pulse trains. The proposed receiver is a simple extension of traditional DFT based coherent pulse train processing. We show that P DFT processors are required to process the staggered train of pulses as a coherent signal, where P is the number of available pulse positions in each pulse repetition interval (PRI). Thus the complexity of the processing hardware only increases linearly with the number of available positions. We also look at the distribution of ambiguity volume around the delay-Doppler map by varying the pulse positions and the selection of pulse shapes.
