Legacy Radar Upgrades

Replacing older radar systems may be considered a cost-prohibitive and high-risk venture. However, as the years go by, maintaining these legacy radars presents its own challenges. In most cases, the antenna and transceiver still operate satisfactorily, but it is the signal processing and computer electronics that become outdated and fail.

In other cases, the radar may still operate; however, the closed nature of the system prohibits information sharing and centralized operation common in modern systems.

SSR’s PCRP Radar Processor can provide a straightforward path to radar system modernization. The PCRP connects into the raw radar signals and performs enhanced signal processing. The legacy radar data is then provided to the rest of the system in a common, open format.

Key Technologies and Solutions

Proven Legacy Integration

SSR provides a low-risk legacy radar upgrade option for both land-based and shipboard surveillance radars. PCRPs have already been fielded to interface to the following list of radars. Interfacing to additional legacy radars can typically be done in a single engineering site visit.

  • AN/SPS-40
  • AN/SPS-42
  • AN/SPS-48
  • AN/SPS-49
  • AN/SPS-55
  • AN/SPS-67
  • AN/SPS-73
  • MK 92 with IFF
Note: This is an unclassified list of sensor integrations – other systems also exist.

AN/SPS-73 Modernization

SSR provides multiple solutions for modernizing existing AN/SPS-73 radars. SSR has an existing PCRP that is a form-fit replacement for the ANS/SPS-73 VME Cage. This replacement can be performed in less than 30 minutes, removing all major failure components and providing a modern Intel / PCI Based architecture, while communication interfaces to all existing systems remain intact.

SSR’s AN/SPS-78 is the USCG’s replacement option for the AN/SPS-73. This system (or a variant) is also available to other agencies as an AN/SPS-73 replacement.

Enhanced Radar Processing

SSR’s radar processing improves the detection capability of standard maritime radars. Automatic clutter processing allows the operator to perform multiple tasks and not focus on tuning the radar. The clutter processing automatically adjusts as storms and other environmental conditions change and the radar processing enhances the detectability of small targets.
