Radar Pulse on Pulse Identification Parallel FFT and Power Envelope Algorithm

Abstract

Identification of pulse radar signals is a crucial component in radar receiver processing. Extracting RF radar pulse information in wideband receivers in a dense and noisy environment without prior knowledge of the signal is challenging in high-risk real-time scenarios. Overlapping radar pulses can create complications in identification by creating interference between the signals, causing loss or hidden information. This paper presents a deinterleaving overlapping radar pulse train process by correlating the pulse descriptor words (PDW) of a power envelope based deinterleaving algorithm with a parallel fast Fourier transform (FFT) based deinterleaving algorithm implemented on an MPSoC FPGA.
