Numerical characterisation of quasi-orthogonal piecewise linear frequency modulated waveforms. 2019 Sensor Signal Processing for Defence Conference (SSPD), Brighton, 9-10 May 2019978-1-7281-0504-8https://doi.org/10.1109/SSPD.2019.8751653http://dspace.lib.cranfield.ac.uk/handle/1826/14440This paper presents an analysis of the Doppler tolerance and isolation properties of five different sets of piecewise linear frequency modulated (PLFM) waveform triplets consisting of a combination of LFM subchirps. Different combinations of PLFM signals are used to produce waveforms with the same time-bandwidth product and optimise them with respect to isolation. The performance of the proposed waveforms are numerically investigated and a comparison between sets is presented. Results confirm that the waveforms have quasi-orthogonal properties and exhibit a degree of Doppler tolerance.enAttribution-NonCommercial 4.0 Internationalhttp://creativecommons.org/licenses/by-nc/4.0/Conference paper
