AN/SPS-11
AN/SPS-11 is operating in the L-Band 3D- air surveillance radar using a stacked beam for measurement of elevation angle. It is designed for installation aboard large Naval vessels to provide height finding and medium range air search.
Basically, the equipment consists of the below decks components of radar set AN/SPS-2 with smaller antenna assembly and stable base than are used in the AN/SPS-2. The antenna assembly consists of a symmetrical split paraboloid reflector fed by seven vertically stacked feed horns each with power splitting coupler for feeding the horn. Power is supplied by a single 10 megawatt magnetron. An IFF and monitor signal antenna are also includes in the system.
