A high cost radar LD6001, it's not cheap, it's about 9 LD2410s and 6 LD2450s. It has these parameters: it supports 8 people simultaneous recognition, and X, Y, Z three-axis positioning. It sounds exaggerated, and so does the price. We thought, at some point, we have to get one to test it! Some simple features: side mounting, maximum distance 8m, up to 8 people, 60G radar.
In the meantime we have sourced a cheap version of the LD6002B which is a 60G radar that has to be ceiling hung and has a range of 3m. These look to be for bath bomb type scenarios. LD6002B simple characteristics: 4 times the price of the LD2410, must be hung high installation, range within 3m or so, hanging height requirements of 2.2m-3m, recognizing the location of the three targets, claimed to be 95% accurate.
