What is it about?
First, There are three different types of optimisation variables, i.e. inter-pulse-frequency,frequency-hopping-order and intra-pulse-phase, in this complex waveform optimization problem. Second, the range-folded clutter is a common problem, but neglected in complex waveform design which usually considering the center autocorrelation sidelobes suppression. In this paper, the recurrent autocorrelation sidelobes, which is the reason to the range-folded clutter, is also suppressed in our optimisation problem.

Why is it important?
The optimisation of three different types of variables and the recurrent autocorrelation sidelobe suppression.
Perspectives
In fact, this optimization problem is not perfect. First, suppressing both the center ACF and the recurrent ACF with the three different types variables jointly will get a better performance. Second, intra-pulse continuous phase modulation instead of intra-pulse phase code will greatly improve the DOFs (degree of freedoms). Thus, the sidelobe performance should be significant improved. If the spectrum constraint is added at the same time, the resulting waveform will obtain spectral compatibility.
