After a fair bit of reading on mmWave sensors I decided to order a DFR C4001 25m presence sensor to test. It works well and I am happy, however in my reading I saw that there are sensors that can track 3 targets simultaneously and give distance and angle and/or X and Y coords for the tracked target. …

[image] Donald_Pittendrigh: DFR unit does not seem to have this ability I assume "the ability" you reference is returning "distance, angle, x/y." How does DFR not have this ability? You know your location (0,0), you measure TOF (d = t * C), you know your angle and find (x, y) with (r = sqrt(…

I lament the seeming inability to read this information from the board. The library for it, seems to offer the following feedback variables :- getTargetEnergy() getTargetNumber() getTargetRange() getTargetSpeed() and I defy you to use those variables to define the location of the object. That …

[image] Donald_Pittendrigh: I defy you to use those variables to define the location of the object getTargetRange() Use distance from getTargetRange() with its relative bearing/angle to find "location" which is relative to "you" [edit] Maybe getTargetEnergy() will show a center of mass? Ina…

There lies the rub, no getTargetAngle() the range is simply a distance from the sensor without which there is no resolution, bearing in mind, as I am sure you know, the sensor covers an angle of 100 degrees. If you know how to read the angle, then the game is on to be sure!!!

[image] Donald_Pittendrigh: no getTargetAngle() Getting an angle assumes a known bearing (of the source). You must set/create that known bearing (of the source) to get the relative angle (of the target). [image] Donald_Pittendrigh: angle of 100 degrees That is where getTargetEnergy() …

[image] xfpd: getTargetEnergy is the measure or the radar energy reflected back from the target, it encompasses neither centre of mass nor direction

[image] Donald_Pittendrigh: it encompasses neither centre of mass What does it encompass, if not (a) mass (a size)? Bats and the blind use echo location to navigate. Why do you deny it works? [image] Donald_Pittendrigh: nor direction (x0, y0) minus (x1, y1) gives direction (and velo…

There was quite a bit of discussion about the HLK LD2451 radar sensor, that gives distance and angles to several targets: Using HLK LD2451 radar for speed measurment
