Mechanical Repair, Finishing and RF Pattern Testing of Lewis Scanner Antennas for

S-Band Lewis Scanner Azimuth Antenna PN: 583Z5001MC-1 and

S-Band Lewis Scanner Elevation Antenna PN: 583Z5001MC-3

1.0 PURPOSE AND APPLICATION

1.1 The purpose of this PWS is to define the mechanical and electrical acceptance standards for overhaul of the S-Band Lewis Scanner Azimuth Antenna PN:

583Z5001MC-1 and S-Band Lewis Scanner Elevation Antenna PN:

583Z5001MC-3 antenna assemblies that are part of the AN/MPS-T1(V) Threat Simulator radar system. Requirements include hardware and electrical functionality as well as mechanical repair, finishing and RF pattern testing.

2.0 BACKGROUND

2.1 This PWS describes the work and services that are required for the inspection, overhaul, testing and repair of the S-Band Lewis Scanner Azimuth (AZ) and Elevation (EL) antennas. Both antennas are identical despite the different part numbers, the only difference being the waveguide mounting hardware. Each antenna assembly is comprised of five sections:

A. Scanner (PN: 583Z5024MC-1): Contains a rotary joint, P/N 2176, that connects to WR284 waveguide.

B. Scanner Cone (PN 583Z5014-1): Comprised of an input parallel plate waveguide section containing an input for the scanner and RF mirror located in the middle of section that directs RF energy as the scanner rotates.

C. Geodesic Lens (PN 583Z5010-1): This is a parallel plate waveguide section containing a sunken curved waveguide path to enhance RF energy direction for beamforming.

D. Asymmetrical Horn (PN 583Z5021-1): This is the output parallel plate waveguide section for directing RF energy onto a reflector.

E. Reflector (PN 583Z5011-1): This is the final output of antenna system. The reflector is approximately 2 FT x 16 FT.

The antennas operate in the 2.9 GHz to 3.1 GHz frequency range and the RF beam is electro-mechanically scanned from (-) 10 degrees to (+) 10 degrees without moving the radar system platform.
