RFbeam Microwave V-LD1 distance sensor

The V-LD1 is an easy to use 61GHz FMCW distance radar sensor with integrated signal processing. No special knowledge in analogue or digital signal processing is needed to adapt the module to different applications resulting in a fast time to market. Transmit frequency and sweep bandwidth are controlled internally and a selection of settings is available to adapt to your application requirements.

The beam width of the module itself is 170 × 60 degrees. However, RFbeam also offers an evaluation kit in combination with a plastic lens that focuses the beam to 8 × 8 degrees, which is  perfect for tank level gauging applications.
