The JRC new X-band VTMS radar is designed to have a solid-state architecture adopting high-power RF devices, allowing stabilized pulse oscillation. This new generation of VTMS radar integrates various signal processing technologies including pulse compression, thereby demonstrating higher radar performance than the conventional magnetron-based radar.
The radar equipment is indispensable for vessels to maintain safety of navigation at sea and the use of radar has recently been increasing more and more. The maintenance cost of magnetron of short service life has been a heavy burden for shipowners. The JRC new radar adopts solid-state devices, which do not need to be replaced every one or two years like magnetron, allowing highly reliable operation to be maintained at a minimum cost.
The demand for microwave band and millimeter wave radar has been growing worldwide and a narrower band has been required. This solid-state radar suppresses the spurious level to a lower value than the magnetron-based radar in order to realize a narrow band and to meet a stricter spurious standard which the magnetron-based radar is hard to meet.
The solid-state X-band radar incorporates new technology in compliance with the IALA V-128 radar performance requirements.
