AN/SPS-58 was operating in L-Band 2D short range air search and target acquisition radar suitable for medium and low altitudes. It was dedicated to detect and countering anti-ship missiles.
The versions SPS-58A to SPS-58D all used a different antenna. All versions used a 2-stage klystron transmitter.
AN/SPS-65 was an upgraded version of AN/SPS-58 using a more powerful transmitter (260 W average) and a longer pulse width (7 µs). The longer pulse duration resulted in a slightly better probability of detection, but worsened the range resolution. The radars pulse repetition frequency was 2 315 or 3 064 Hz.
