AN/CPS Series Radars

References:

AN/CPS-1

Type: Air Transportable; Microwave Early Warning (MEW) Radar
Manufacturer: General Electric
IEEE Band: S Band
NATO Band: F Band
Exact Frequency: 3200 MHz
Maximum Instrumented Range: 200 miles
Power Required: 23 kw from portable generator
Antenna Weight: 5 tons
Scanning Rate: 10 rpm

Notes: Complete installation weighs 66 tons. When it is necessary to make it mobile, 10 trucks are required for MEW gear and 6 more for VHF installation. Ready for travel in 1.5 days.

AN/CPS-2

Type: Air Transportable; Early Warning; medium-range radar
Manufacturer: Federal Telephone and Radio Corp
IEEE Band: L Band
NATO Band: C Band
Exact Frequency: 510 – 725 MHz

Notes: Project 424B at Camp Evans Signal Laboratory 1943.

AN/CPS-4

Type: Air Transportable; Height Finder
IEEE Band: S Band
NATO Band: E Band
Exact Frequency: 2700 – 2900 MHz
Maximum Instrumented Range: Possibly 90~ miles.
Operators: 6

Notes: AN/CPS-4 was designed to be used in conjunction with the SCR-270 and SCR-271 search sets, and was often paired with the AN/FPS-3 search radar in the 1950s.

AN/CPS-5

Type: Air Transportable GCI Radar
Manufacturer: General Electric & Bendix
IEEE Band: L Band
NATO Band: D Band
Exact Frequency: 1300 MHz
Pulse Repetition Frequency: 400 pps
Pulse Width: 2 microseconds
Peak Power: 750 kilowatts
Maximum Instrumented Range: 60 miles (in operation aircraft were picked up as far as 210 miles)
Maximum Altitude: 40,000 feet
System Weight: 40,000 pounds
Operators: Five men required: PPI operator, A-Scan operator, Plotter teller, Recorder and radar repairman

Notes: Production began January 1945. Used with AN/TPS-10.

AN/CPS-6

Type: Air Transportable Search & GCI Radar
Manufacturer: General Electric
IEEE Band: S Band
NATO Band: F Band
Exact Frequency: 3200 MHz
Pulse Repetition Frequency: 300 or 600 pps
Pulse Width: 1 or 2 microseconds
Peak Power: 2 megawatts
Detection Example: Fighter aircraft at 16,000 feet at 100 miles (initial design role)
Operators: 25

Notes: First units produced mid-1945. Consisted of two antennas; one in a height finder role and the other in a search role.
