AN/SPS-40

The AN/SPS-40 is a ship -based 2D air search radar room with great range. It was manufactured by the U.S. company Lockheed, Sperry Corporation, Westinghouse Norden Systems.

Description

The SPS -40 was derived from the AN/SPS-31 and replaced the AN/SPS-6 and AN/SPS-29 and was introduced in 1961. It has a digital MTI - mode, pulse compression, integrated IFF interrogator and special modes for low-flying targets. The first models were considered to be relatively unreliable, but this, however, changed with the introduction of more advanced versions. By now, most models have been retired and replaced by the AN/SPS-49.

Variants

  • AN/SPS-40: The basic version, produced by Lockheed.
  • AN/SPS-40A: Slightly modified version, made ​​by Sperry
  • AN/SPS-40B: From this variant IFF system is integrated. 43 systems were manufactured by Norden Systems.
  • AN/SPS-40C: Version with improved detection of low-flying aircraft and enhanced ECCM capabilities.
  • AN/SPS-40D: This is a modified version of the A - variant whose reliability could be significantly increased. It can also be integrated into the AN/SYS-1 combat system. It was produced by Westinghouse.
  • AN/SPS-40E: Although this version of Norden Systems has already brought to series production, the U.S. Navy suspended funding.

Meanwhile, a modernization of the E variant is offered, which replaces the analog traveling wave tubes with new, digital semiconductor components. This is intended to increase the performance and the reliability can be increased.
