Abstract :
A modification to the Costas signal is suggested. It involves an increase of the frequency separation Δf beyond the inverse of the subpulse duration tb combined with adding linear FM (LFM) with bandwidth B, in each subpulse. Specific relationships between Δf and B will prevent autocorrelation grating lobes, that would normally appear when tbΔf>1.
