The LDTGSS01 is a specialized 24GHz Doppler radar sensor designed specifically for low-speed ground speed measurement in agricultural and industrial applications. Engineered as a K-band radar sensor module with CW operating mode, this millimeter wave radar sensor delivers accurate speed detection from as low as 0.1m/s, making it ideal for tractors, harvesters, and other off-road vehicles. With a Pulse interface that benchmarks against traditional pulse velocity sensors, the LDTGSS01 offers a modern radar-based alternative for precision ground speed monitoring.
1. Advanced 24GHz Radar Technology for Low-Speed Measurement
As a sophisticated 24GHz microwave radar sensor, the LDTGSS01 utilizes K-band RF integrated circuit design with CW operating mode, providing reliable ground speed radar measurement in challenging agricultural environments. This radar speed sensor features a narrow 15°×15° beamwidth (-3dB) with excellent side lobe suppression of 18dB, ensuring focused detection on the ground surface. The system delivers exceptional low-speed sensitivity with a minimum detection threshold of 0.1m/s, significantly outperforming traditional wheel-based sensors that struggle at low speeds.

3. Installation Guidelines
3.1 Recommended Installation
-
Mount on the vehicle undercarriage with antenna facing the ground
-
Recommended height: approximately 0.8 ~ 1 meter from the ground
-
Installation angle: 35° between antenna surface and ground
-
Sensor can face forward or backward
3.2 Mounting Requirements
-
