Are you talking about phased array antennas? Usually beams are formed at the same time by weighting outputs of the different antenna elements, allowing for directivity of the elements. The processing therefore provides simultaneous measurements in bearing on all targets from which energy is received. I don't know what you mean by 'enhancing the execution time up to the simultaneous approach time.' Please clarify.

Thanks for your contribution , yes , certainly I meant the phased array antennas (PAA), further more I'm talking about its major two types : single beam PAA (sequential search & tracking : Track-While-Scan " TWS" ) , and the multiple beam PAA ( multiple targets simultaneous tracking ) ! so the question is : can we enhance the TWS performance to be equal to the second type and how ? are there any other suggested alternatives ?! by the way , what you had explained , it's the single beam forming and steering method , the multiple beam PAA is the advanced fully adaptive PAA , which I'd expressed as a simultaneous tracking PAA , thanks a lot !

First, it is possible to parallelize the computation. Secondly, here are the links:
