smartmicro automotive radar UMRR-11 Type 132
The smartmicro UMRR-11 Type 132 Automotive sensor is a high-performance front and rear radar, featuring 4D/UHD capabilities. The 76-77GHz sensor has a range of up to 175m and a 100-degree field of view. Its antenna aims at long range and wide horizontal angular coverage, providing both long- and medium-range mode. Due to its small size as well as the lightweight and very robust housing, the sensor can be used for multiple automotive applications. The smartmicro radar sensor works in adverse conditions, is almost unaffected by weather, independent of sunlight, and works in a wide temperature interval.

1 Optionally, the minimum range can be reduced for customer-specific needs that depend on local frequency regulations. ↩
2 Typical values; all values given for bore sight; they may vary depending on the clutter environment. Please note that the radar system can neither achieve a detection probability of 100% nor a false alarm rate equal to zero. ↩
3 The total field of view is an angle interval in which reflectors can be detected; 3dB field of view is narrower. ↩
4 The typical value is measured at a target output level at bore sight, for a point reflector showing >23dB SNR. Errors may increase towards larger angles. ↩
5 Measured at the connector. ↩
6 Power consumption at 20°C. ↩
7 It is recommended to use an external surge protection for power, CAN, RS485, Ethernet and other interface ports. ↩
