WebDec 1, 2024 · I have done some work with wigner distributions, but I recently started using choi williams distributions. I am unsure as to what sigma I should use. When I use the present value of 0.05 all my useful information disappears. From what I understand this means that the signal being removed is all cross-term. Why do I not want this. WebThe Choi-Williams distribution is a mathematical technique that was first created using MATLAB and then converted to C code for use on the SRC-6. The purpose of this study is to investigate the feasibility of using a reconfigurable computer for ELINT applications and the timely detection and classification of LPI signals.
