一个信号恢复技术的动机和衍生的几个非负信号的自相关和互相关函数的测量恢复。示出的迭代技术，以保持非负的信号估计，并产生一个序列的估计，其相关性更好地近似所测得的相关性的迭代进行。仿真结果表明，该方法是有效的。
A signal recovery technique is motivated and derived for the recovery of several nonnegative signals from measurements of their autocorrelation and cross-correlation functions. The iterative technique is shown to preserve nonnegativity of the signal estimates and to produce a sequence of estimates whose correlations better approximate the measured correlations as the iterations proceed. The method is demonstrated on simulated data for active imaging with dual-frequency or dual-polarization illumination.
