The Mid-Year Challenge: When 24GHz and 80GHz Hit the Wall
As of June 2026, the intensification of flash floods in Oman’s Wadis, the Himalayas of India, and the narrow drainage canals of Manila has exposed a critical limitation in standard radar sensors.
In these “cramped” environments, traditional 24GHz (and even 80GHz) radar sensors often suffer from Multipath Interference. Wide beam angles cause the signal to bounce off rock walls, manhole ladders, or overhanging bridge structures, creating “ghost echoes” that render water level and velocity data useless during a storm.
To build a reliable 2026 Early Warning System (EWS) in high-stakes terrain, the industry is shifting to 120GHz FMCW technology.
The Perception Layer: 120GHz Millimeter-Wave Superiority
Honde Technology’s 120GHz 3-in-1 Radar Flow Meter utilizes the extreme high-frequency spectrum to achieve physical performance previously impossible in hydrology:
1. Ultra-Narrow 4-6° Beam Angle
By using a 120GHz carrier frequency, the radar beam is concentrated into a surgical “pencil beam.” The Advantage: It ignores bridge pillars and vertical walls just 20cm away from the probe.
2. FMCW + Doppler 3-in-1 Integration
This single IP68 unit integrates Water Level, Surface Velocity, and Flow Rate calculations. Stability: The FMCW architecture provides massive sweep bandwidth to “see” through heavy mist and intense rain.
3. CE-Certified Industrial Reliability
Built with high-grade components, the sensor is immune to high ambient temperatures and humid salt-air environments.
