AN/SPS-64

The AN/SPS-64 Mariners Pathfinder radar is a versatile surface search and navigation radar with raster scan bright display indicators, and offers enhanced operational characteristics. The AN/SPS-64(V) is supplied in X-Band (9,375-9,420 MHz) or S-Band (3,030 MHz) versions with a choice of relative, true motion and collision avoidance displays. Plan Position Indicator displays of 30 cm and 41 cm are the basic configuration with expansion options and accessories available for the majority of requirements. The RAYCAS V indicator combines the presentation of radar information with collision avoidance, target tracking, navigation and tactical data on a 41 cm display. The RAYPATH indicator combines radar information, collision avoidance and navigation data on either a 30 cm or a 41 cm bright display. These commercial, large ship radar systems have demonstrated high reliability and performance, while offering a most cost-effective radar system for all types of naval vessels.

By offering a totally compatible choice of antennas; 25, 50 and 60 kW transmitters; and display indicators, over 15 different radar configurations are available. The fully modular design allows duplication of systems when required, and intermixing of displays and transceivers in any combination. With an adaptive interface capability the suite of displays can be used with other radar systems. Interfaces for the AN/SPA-25 and AN/SPA-66 are available, as well as interfaces for fire control, and electronic support measures systems.

The variants are combinations of the basic radar with different antennas, displays and interface units tailored to the needs of the ships carrying them.
