Abstract
This paper presents a comparison of the available electronic techniques for distance measurement suitable for the off-highway environment. The main techniques described are:
-
ultrasonic
-
passive infrared
-
laser radar
-
FMCW radar
-
impulse radar
-
capacitive
-
vision
The techniques are compared across a number of key parameters, including sensitivity, measurement range and cost. A brief description of some of the disadvantages is also included. Finally the paper discusses the use of sensor fusion techniques to overcome the inherent disadvantages of particular techniques.
