Naval Radar Surveillance

The Terma radar is the only radar sensor providing simultaneous small target detection and helicopter guidance. 

Terma's SCANTER X-band Navigation, Surface Search and Short Range Air Surveillance Radar Systems are complete radar sensor systems with proven small target detection capability to assist authorities in efficiently monitoring illegal activities such as drug trafficking, smuggling, illegal immigrants, piracy, illicit fishing, terrorism, etc. It is perfectly suited for high-definition sea surface surveillance and short-range air surveillance for helicopter control and ship navigation.

At an affordable price, the SCANTER radar systems are specifically designed to enter service where the commercial marine radar fails to meet the requirements for noise and interference rejection, signal processing, electronic interfacing, signal distribution, and resistance to a tough environment. 
Terma A/S has accumulated a deep and thorough know-how about radar sensor technology comprising advanced signal processing and high performance antennas specifically tailored for small target detection in rough weather conditions. Terma's SCANTER naval radar sensors are operational in navies worldwide.
A versatile and modular concept ensures compliance with application requirements and specific customer wishes. The Receiver-Transmitter (RxTx) system configuration ranges from single frequency operation to RxTx systems with frequency diversity.
The SCANTER naval radar systems comply with the justification and operational requirements on board naval vessels to:

  • Provide backup to primary surveillance radar system
  • Assist on-board tactical task functions
  • Helicopter landing control
  • Perform sea and short-range air surveillance with automatic target tracking
  • Provide versatile interface capability for C-Flex and other on-board systems
  • Provide safe navigation for year-round operation.

Compared with systems with higher transmitter output power, the increased sensitivity and high dynamic range of the SCANTER radar system is advantageous, especially considering:

  • The need to minimize radar emission while optimizing target range detection
  • The avoidance of receiver saturation in case of jamming.

Within the market segment Submarine Application, Terma has participated in a number of projects throughout the years and recently designed a radar sensor system, SCANTER 2002, specifically optimized for submarine application.
