Abstract: The designing of step frequency signal is concerned.Stochastic sequence step frequency signal is advanced to overcome the ordered step frequency signal s default of range-velocity coupling. The advanced signal is better than the ordered step frequency in clutter rejection and range-velocity resolution. -
