Hi, i’ve finally gotten my hands on a Ping360! I am currently working out how to understand the specifications of the device. I will be using the data for complex navigation. I therefore have some quite specific (and technical) questions:
The device has a range resolution of 0.08%. I am a bit usure how to interpet this. A 50 m, this gives ca. 4 cm. Does this resolution make it impossible to tell and object that is 47 meters away from and object that is 50 meters away? Or is this the resolution slant range. I.E if two objects are 3 cm away from each other and both are 50 m away from you, then you can’t tell them apart.
Basically: what can you define the resolution in terms of polar coordinates?
Is the angular precision better when combining measurements? I notice that the mechanical resolution is 0.9 deg, while the horizontal beam is 2 deg.
Why is the scan speed different at 2 m than at 50 m? Wouldn’t the sonar scan for all ranges (2-50 meters) at all times? And wouldn’t that imply a constant scan speed? Or can i somehow limit my range to 2 meters to improve scan speed?
Third, does the vertical and horizontal bandwidth define the size of the slant angle?
And lastly: is it possible to get some data on the measurement noise?
