According to Meteopress, solid-state C-band radars are leading the way in the innovation of weather radars. With large manufacturers stepping in, and with problems like blind range mitigation successfully solved, it is time to reap the benefits of the technology. The benefits of solid-state radars are numerous, including financial, operational and practical advantages.
The practical advantages include large flexibility of the radar operation, compactness of the system, low power needs and ultra-low maintenance needs. The flexibility of operation comes from the software-defined signal processing unit, the backbone of the radar. The pulses can vary from scan to scan, enabling operators to fine-tune the pulses to the target, length, elevation and status of the atmosphere. Meteopress’s state-of-the-art wi-fi suppression system also ensures the radars can operate within large cities.
Software-based radars can also solve previously unsolvable problems – like limited Doppler speeds. Meteopress intends to introduce a radar with measurable Doppler speeds of 1000 km/h. The solid-state status and the compactness of the system are expected to bring major operational advantages. When constructing the radar infrastructure, operators can use super-light structures. Additionally, no specified radar room is necessary and everything is housed in the radome. With limited moving parts, only minimum maintenance is needed. The electricity needed for current Meteopress C-band radars is about 600W, which cuts the need for high voltage and enables solar-powered radar systems to be sustainable and deployable anywhere in the world.
Finally, the proposed financial advantages stem from the practical and operational advantages. The solution’s lower purchase cost, lower deployment costs and ultra-low operational costs bring the total cost of ownership of the radar to about 20-30% of previous C-band radar projects.
