AN/SPS-52
The AN/SPS-52 is a ship -based 3D air surveillance radar with a long range. It was produced by the U.S. company Hughes.
Description
The SPS -52 was developed in the 1960s based on the AN/SPS-39 and consequently used for height -finding radar targets also the so-called "Frequency scanning" technology ( FRESCAN ). This is sent to a wide range of frequencies. A "scan " process begins with a high frequency, which results in that the radar signals are transmitted from the lower part of the antenna. Now, the frequency is reduced and the location of the radiation travels to the antenna surface facing up. This causes the angle changed for radar target, resulting ultimately its height can be calculated. Although this method has the advantage that it does not require additional mechanical components to the level determination and has a higher EloGM resistance, it is however a relatively large and unwieldy antenna required to ensure accurate positioning.
The system is digitized to a large extent, has an MTI mode of operation and can be integrated into the AN/SYS-1 combat system. In some radars IFF device has been added, which can be found on the main antenna. The SPS - 52 was, at least in the U.S. Navy, retired and completely replaced by the AN/SPS-48.

Variants
- AN/SPS-52A: The basic version.
- AN/SPS-52B: unspecified improvements have been performed in this variant.
- AN/SPS-52C: This is a major upgrade, which was put into service in 1978 and can now be connected to the AN/SYS-2 combat system. The system is now fully digitized and achieved through a comprehensive modernization Electronics longer ranges. Also in reliability and resistance to interference improvements have been made.
