The AN/TPS-43 radar set

The AN/TPS-43 is a transportable 3-dimensional air search radar produced in the United States originally by Westinghouse Defense and Electronic Division, which was later purchased by Northrop-Grumman.

Description

This section needs expansion. You can help by making an edit requestadding to it . (January 2015)

The AN/TPS-43 is a ground-based, non-fixed (i.e.: transportable) search radar.

The entire system can be broken down and packed into two M35 trucks for road transport. The TPS-43E2 was redesignated the AN/TPS-75 which is the current transportable air control and warning (AC&W) radar used by the United States Air Force.

Variants

In addition to the basic TPS-43 several variants were developed.

  • TPS-43A (antenna tilt; new IFF)
  • TPS-43B (enlarged shelter; changes to transmitter)
  • TPS-43C / 43CX (increased reliability; IFF improvements)
  • TPS-43D / 43DX (ISLS added; maximum detection range increased)
  • TPS-43E (major redesign; improvements to electronics, mechanics and shelter)
  • TPS-43F / subvariants V1 to V6 (major redesign; enlarged shelter, improved electronics; increased reliability)
  • TPS-43G (4MW version designed for Pakistan)
  • TPS-43M (improved electronics; increased dynamic range; improved IFF incorporating several modules in a single unit)
  • TPS-430

Operational History

The AN/TPS-43 completed development in 1963 and entered US service in 1968.

The reciprocal of PRF (or PRR) is called the pulse repetition time (PRT), pulse repetition interval (PRI), or inter-pulse period (IPP), which is the elapsed time from the beginning of one pulse to the beginning of the next pulse. The IPP term is normally used when referring to the quantity of PRT periods to be processed digitally. Each PRT having a fixed number of range gates, but not all of them being used. For example, the APY-1 radar used 128 IPP's with a fixed 50 range gates, producing 128 Doppler filters using an FFT. The different number of range gates on each of the five PRF's all being less than 50.

Within radar technology PRF is important since it determines the maximum target range (Rmax) and maximum Doppler velocity (Vmax) that can be accurately determined by the radar. Conversely, a high PRR/PRF can enhance target discrimination of nearer objects, such as a periscope or fast moving missile. This leads to use of low PRRs for search radar, and very high PRFs for fire control radars. Many dual-purpose and navigation radars—especially naval designs with variable PRRs—allow a skilled operator to adjust PRR to enhance and clarify the radar picture—for example in bad sea states where wave action generates false returns, and in general for less clutter, or perhaps a better return signal off a prominent landscape feature This radar was deployed by the Argentine Air Force during the 1982 Falklands War to Stanley and survived two British attacks with AGM-45 Shrike anti radar missiles on May 31 and June 3. One of the radars was captured by British forces after the Argentine surrender and deployed at RAF Buchan Another set installed at Rio Grande, in the mainland, was used to guide Argentine attacks on the British fleet.
