Overview
The SR237-8500C Coastal Surveillance Radar is the flagship of the SR237 series, delivering reliable long-range maritime domain awareness. Equipped with advanced MIMO (Multiple-Input Multiple-Output) and DBF (Digital Beamforming) technology, it provides superior sea-clutter suppression and minimizes false alarms even in complex coastal environments.
Designed for vessel detection, early warning, and target cueing, the SR237-8500C is ideal for ports, coastal defense lines, offshore platforms, and inland waterways. With its phased-array electronic scanning and wide coverage, operators can maintain situational awareness across large sea areas while responding quickly to emerging threats or anomalies.
Key Features
- Long-range vessel detection: Effective monitoring out to 8.5 km with stable tracking performance.
- Real-time monitoring: Continuous scanning ensures immediate awareness of vessel movements and abnormal activities.
- Fast-moving target tracking: High frame rate supports stable tracking of both conventional vessels and fast boats.
- Multi-radar networking: Supports deployment of multiple arrays to create extended, layered surveillance zones.
- Compact & easy installation: Pole or structure mounting with low power consumption and simplified logistics.
- All-weather operation: Reliable 24/7 performance, unaffected by night, rain, snow, fog, haze, or dust.

FAQ
Q1: Can SR237-8500C integrate with other systems?
A1: Yes. The SR237-8500C provides open Ethernet UDP target data output, enabling straightforward integration with third-party platforms such as VMS, PSIM, and C2 systems. The radar transmits standard target information—position, speed, heading, and track ID—in a defined data structure. Integration typically requires the partner’s software team to parse this data according to the protocol specifications, which can also be provided in standalone form upon request. All message formats, field definitions, and examples are listed here: Communication Protocol.
Q2: Can multiple SR237-8500C units operate as a network?
A2: Absolutely. The radar supports multi-node networking over standard Ethernet.
Each unit can transmit its target tracks to a central server for multi-radar fusion and cooperative tracking.
Time synchronization is achieved through NTP or GPS-based clock alignment, ensuring accurate cross-site data correlation and unified situational awareness across wide coastal areas.
Q3: What anti-interference and signal-processing features does the radar employ?
A3: The SR237-8500C incorporates Digital Beamforming (DBF) and adaptive MTD/CFAR algorithms for clutter suppression and interference rejection.
It dynamically filters out sea-clutter and rain-clutter, while the frequency-agile transceiver and automatic gain control (AGC) maintain reliable performance under dense electromagnetic environments. This enables consistent detection of low-RCS targets even near large vessels or strong wave reflections.
Q4: Can the radar output be used to cue EO/IR cameras in real time?
A4: Yes. Each radar track includes precise bearing and range information updated multiple times per second.
These coordinates can be transmitted through the integration protocol to automatically cue EO/IR or PTZ camera systems for visual confirmation and tracking. This “radar-to-EO handoff” capability is essential for coastal security operations requiring rapid identification of small surface targets.
