  We investigate the constant-modulus (CM) waveform design for dual-function
radar communication systems in the presence of clutter.To minimize the
interference power and enhance the target acquisition performance, we use the
signal-to-interference-plus-noise-ratio as the design metric.In addition, to
ensure the quality of the service for each communication user, we enforce a
constraint on the synthesis error of every communication signals.An iterative
algorithm, which is based on cyclic optimization, Dinkinbach's transform, and
alternating direction of method of multipliers, is proposed to tackle the
encountered non-convex optimization problem.Simulations illustrate that the CM
waveforms synthesized by the proposed algorithm allow to suppress the clutter
efficiently and control the synthesis error of communication signals to a low
level.
