- Abstract
An affordable phased array for a ship self-defense experimental engagement radar is described. The array used a hybrid approach by combining a slotted waveguide array with phase shifters at each column to provide scanning in the azimuth plane and a Radant lens placed in front of the slotted array to provide independent scanning in the elevation plane. The approach avoids using a phase shifter or a T/R module behind each radiating element and simplifies beam steering using row-column controls which reduce the phased array cost. The production cost of the proposed array is estimated to be less than one-third the cost of a similar sized array using a phase shifter or T/R module behind each radiating element. Recently, a 4' x 8' Radant lens was procured from Radant Technologies, Inc. and placed in front of the existing (modified AN/TPQ-36) phased array. This paper reports on the results of this hybrid array., Prepared in collaboration with Sachs Freeman Associates, Largo, MD and Radant Technologies, Inc., Stow, MA.
