Advanced VTS and Coastal Surveillance Radar Technology V. INFORMATION DOCUMENT Mark Bown - Group Marketing Manager at Kelvin Hughes discusses the potential benefits of a dual X-Band and S-Band VTS or coastal surveillance radar.

SITUATIONAL INTELLIGENCE, THE WORLD OVER Advanced VTS and Coastal Surveillance Radar Technology Choosing a Vessel Traffic Service (VTS) or Coastal Surveillance solution is often a difficult process. Deciding which radar sensor is right for your application can be a challenging task. Having chosen the right technology it is also necessary to ensure there are adequate sensors in place to achieve the system objectives. With high expectations and, in many cases tight budgets, the decision process to get the best value for money can be a complicated business. For systems requiring ‘standard’ and...

For example, while the X-Band frequency is best suited to providing an acceptable level of range and bearing discrimination, its performance in rain cannot match the S-Band. This is not because X-Band is technically inferior but simply the physical properties of rain i.e. the reflection and attenuation coefficients of the droplets of water with respect to the X-Band frequency have a degrading effect. The effect experienced is the same for any X-Band radar. In areas experiencing high rainfall, the only option previously was to invest in two separate radar systems including the tower and...

cure, the wide frequency diversity of the two bands offer an increased chance of combatting the problem. Evaporation duct traps radio energy and creates a duct for the signal to travel following the curvature of the earth. This can occur at varying altitudes. A mast at 70m above sea level may well have evaporation and duct forming just below that Figure 3 - Ducting infographic Just about any coastline radar project within the tropics will be subject to either frequent heavy rain or ducting or both. Often an X-Band radar is chosen as this will be the best compromise for the majority of the...

The outcome is an optimised combination of transceivers but without all the additional cost of a stronger and wider mast that two separate systems would demand. The SBS 900-4 has a 5.5m X-Band antenna combined with a 3.9m S-Band antenna. The SharpEye™ X-Band deploys Doppler processing, Frequency Diversity (FD) and high resolution pulse compression techniques. The SharpEye™ S-Band also features Doppler processing and high resolution pulse compression techniques. The overall performance is enhanced further by the co-located ‘X and S’ band antennas simultaneously transmitting both frequencies....

SharpEye™ uses solid state components that easily exceed the life of a conventional radar. SharpEye™ uses solid state components that easily exceed the life of a conventional radar. Not only is the need for routine maintenance removed, such as changing the magnetron every year, but the transceiver reliability of at least 150,000 hours between failures (17 years) results in a reduced through life cost of ownership and reduced downtime. SharpEye™ uses a patented sequence of coded and varying length pulses to help ensure target fidelity at all ranges. Figure 6 - SharpEye™ X-Band Transceiver...
