AN/SPS-52

The SPS-52 Navy shipboard 3-D Air Search radar is a very long range search radar with medium detection probability. As frequency is varied, the radar's beam axis changes, and scanning can be accomplished in one axis (either elevation or azimuth). Variation in frequency tends to make this radars more resistant to jamming than if operated at a fixed frequency, and it also provides a solution to the blind speed problem in MTI systems. Frequency scanning does impose some limitations in that a large portion of the available frequency band is used for scanning rather than to optimize resolution of targets. Additionally, this imposes the requirement that the receiver bandwidth be extremely wide or that the receiver be capable of shifting the center of a narrower bandwidth with the transmitted frequency.
