422                                             AIR TRANSPORTABLE RADAR FOR AIRCRAFT WARNING AND GCI.

422A                                          MICROWAVE EARLY WARNING SET (RADIO SET AN/CPS-1).

                                                   DESCRIPTION: A 3000-mc air-transportable, early-warning ground set which, when
                                                   mounted about 100 feet above level terrain, will detect low-flying aircraft from
                                                   5 to 30 miles, and high-flying bombardment aircraft up to 175 miles. presentation
                                                   PPI, “A” and “B” types. Intended for use under all climatic conditions and temperatures from -400 to +120 F.

                                                   MILITARY CHARACTERISTICS (Revised): Letter from OCSigO, 22 July 43, file SPSRB
                                                   413.44 AN/CPS-1.


                                                   1. General.

                                                   a. Observations of prototype of MEW at Tarpon Springs, Fla.,
                                                   indicate satisfactory results. Nine thousand to 11,000 targets
                                                   were plotted in eight hours, some targets as far away as 160
                                                   to 180 miles. This is considered excellent in view of the fact
                                                   that personnel operating this set was not thoroughly experienced.

                                                   b. Final specifications for Radio Set AN/CPS-1 have been
                                                   completed and forwarded to the General Electric Co.

                                                   2. Frequency Change Kit CPSI-Q1.

                                                   C. The development of the frequency change kit is under
                                                   consideration for use with Radio Set AN/CPS-1. The kit will
                                                   consist of the necessary materials and equipment to effect
                                                   frequency change in the radio set from the “S” band to the “L”

422B                                          TRANSPORTABLE GCI SET (RADIO SET SCR-636-A).
