Abstract :
A coherent train of identical linear-FM pulses is a popular radar signal, mainly due to its good range and Doppler resolution. One of its drawbacks is the relatively high autocorrelation function (ACF) sidelobes. We show how to completely remove most of the sidelobes by diversifying the pulses through overlaying them with orthogonal coding. The technique applies to any other type of pulses - analog or digital.
