System and method for processing the signals radiated in the noise environment from the target signal source

摘要

The stage which as for this invention, as for this method, in order that at least one beam formation vessel output signal y ' _i (n) (i=1 - N) it forms, the beam formation vessel (30I and 30II) following to the filter factor which defines the specified filter quality of desire, receives the signal transducer array (10) the intended signal source which is categorized to intended signal source direction _s (20) from in regard to the system and the method of processing the signal which is emitted in noise environment, conversion, and filtering it does; The control signal t which displays intended signal source direction _s (n) the stage which is formed; It has possessed. This kind of system and method with the minimum operational quantity and memory capacity in order for reception of the clear signal to actualize in all intended signal source directions _s, the fact that it improves is purpose of this invention. This purpose, as the beam formation vessel (30I and 30II) intended signal source (20) had the specified filtering quality of business in intended signal source direction _s, control signal t (n) responding, is actualized by offering the adjustment possible filter factor which is formed.
