This is often experienced when an emergency vehicle drives past with its siren blaring. Our interactive map allows you to see the local & national weather Garmin’s Fantom™ radar is available in 4' and 6' array sizes, both rated at a 72 nm range (but given the curvature of the Earth, the effective distance that an objected can be detected is much shorter). Since FMCW constantly builds up radar return energy (vs. a single “main bang” transmitted by a pulse radar), this system provides target detection superior to pulse radars while transmitting at far lower energy levels. The difference between the currently transmitted and received frequencies, coupled with the known rate of frequency increase, is how these radars precisely calculate a “time of flight” and target distance. The term RADAR is an acronym made up of the words: RAdio (Aim)° (Aim) Detecting And Ranging. Also, there’s no more waiting for warmup time. This method of generating several kilowatts of pulsed energy has to be coupled with a relatively wide-bandwidth receiver. This provides a more complete picture of targets in the atmosphere, allowing forecasters to differentiate between rain, snow/melting snow, and even hail.

The radar set then turns off its transmitter, turns on its receiver and listens for an echo. Raymarine calls it a CHIRP pulse compression radar. Sold-state radomes are available from Raymarine, Simrad, B&G, Lowrance and Garmin. Raymarine’s Quantum radome is a 24-mile radar, compatible with their Axiom series. Simrad’s HALO open array comes in 3' (48 nm), 4' (64 nm) and 6' (72 nm) array widths. Garmin’s Fantom™ Pulse Compression Radar uses the Doppler effect to highlight fast-moving targets. Since this time, the modern weather radar has evolved and improved a great deal, incorporating better data retrieval methods and higher resolution data. By the start of World War II, many countries used it to detect enemy ships and aircrafts. Think about the future potential of having your whole boat wireless—how much easier is it going to be to install and upgrade electronics down the road.” Considering what wireless connectivity has done for software upgrades, radar is a good place to start due to rigging challenges. Solid-state radars also transmit at a very low power level, a few Watts or less compared to kilowatts for traditional radar, yet they place more energy on the targets and generate sharper returns. [A magnetron radar] pulls something to the tune of 60 watts, which is a good amount of power on a battery-based system.

It transmits for roughly ten times as long as a conventional pulse radar, which helps explain how a solid-state, broadband radar transmits more energy onto a target and achieves a sharper return. Meanwhile, the transmitter continues to output an increasing frequency. Solid-state transmits at lower power but it uses up to 10 percent of the duty cycle.” Furuno is excited about the fast-tracking system. The R&D departments of these various companies have been working to pack these new systems with enhanced functionality and improved target resolution while using less power and emitting less possibly dangerous microwave emissions around your boat. 103 Mountain Court,  This solid-state radar uses pulse compression to focus energy on targets and improve resolution on the display, while optimizing technology that uses the Doppler effect to capitalize on relative motion of targets. Known as Halo, the system is a powerful open-array solution that brought the company’s development of the technology to the next level (See our full coverage of those systems here and here).
