OmniPreSense is back at it and has released a new FMCW range reporting radar, the OPS241-B. Like the OPS241-A, which is a Doppler radar, the OPS241-B reports the range to objects in its field of view. But not just one object, it will give you the reading for up to 9 different objects in its field of view. And you can get the signal magnitude from the sensor so you have a sense of the size of the object. You may be able to tell the difference between a wall your robot may run into or a person approaching. The OPS241-B can detect people up to 8m (26 ft.) away, cars up to 15m (49 ft.), and the wall of a build up to 20m (66 ft.). It does all this with a fairly tight 7.5cm range resolution.
