Power-Aperture Product, Efficiency, Signal to Noise Ratio and Search Function Time of Weighted Phased Arrays

The power-aperture product and efficiency of weighted phased arrays is examined for various windows. The impact on the signal to noise ratio is also investigated for the use of windows on the transmit and receive modes of operation of the array and we examine the dependence of the search function time on the array windows. In determining the search function time to conduct surveillance over a given region of space it is necessary to obtain the surveillance solid angle which we obtain via an integral solution.
