Interference problems expected when solid-state marine radars will come into widespread use

The increasing environmental consciousness and the better attention being paid to the primary resources (especially oil and raw materials) is one of the main drivers of the increase in vessel traffic. Moreover, sea shipping is characterized by a good delivery rate and by affordable operating costs in comparison with other transport means, i.e. by road, rail or air. For this reasons, the continuous increase of vessel traffic requires a high degree of control and an adequate assistance to the navigation, in order to ensure safety, reduction of risks for the environment, as well as an efficient, quick and comfortable navigation. The paper describes the evolution of the marine radar systems pointing out the advantages and the potential drawbacks due to the implementation of solid state technology in the incoming, new generation solid-state, high duty cycle marine radars.
