Embodiment Construction
[0026] The present invention is described in more detail below in conjunction with accompanying drawing example:
[0027] 1. There is an array composed of M array elements to receive P broadband stationary random signals located in the far field. When there is additive noise, the signal received by the mth array element can be expressed as:
[0028] x m ( t ) = Σ p = 1 P s p [ t - τ m ( θ p ) ] + n m ( t ) - - - ( 1 )
[0029] where m=1, 2·,...
