Optimal Unimodular Sequences Design Method for Active Sensing Systems

Algorithm 2

PWCIA (Periodic correlation Weighted Cyclic Iteration Algorithm).

Set the to an initial value; and select the desired weights ;

Set ;

Compute ; ;

Compute the exchanged vectors and according to (17); Compute

according to (23);

Compute ; and get the target function ;

Obtain the optimal solution to the one-dimensional problem (26) according to (27) for

continuous phase case or according to (30) for finite phase case.

Update ;

Judge , if , return to step ; otherwise turn to step .

If , where is a predefined threshold to control convergence, output ;

otherwise, , return to step until convergence.
