Abstract

This study aims to examine the effect angle of incidence has on REDM to better understand REDM technology and its capabilities. Three key areas were chosen to specifically focus on; analysing the effects of combined angle of incidence, analysing two face observations and determining if there is a critical angle of incidence. The research was justified based off the lack of previous research into combined angle of incidence and taking two face REDM observations

A testing regime was incorporated into the research testing a large variety of incident angles across three distance ranges of 10, 30 and 60 metres. At each distance range incident angles between 25 -75⁰ were analysed using 5⁰ increments to create trend lines and accurately model how incident angle error behaved. A reflectorless target was crucial to the research and was constructed to match the properties of Kodak grey cards reflective side.

The critical angle of incidence was found to be 60⁰ and the maximum recommended angle of incidence was found to be 35⁰. The second and major finding from the study was the degree of improvement two face observations make to REDM accuracy. Results showed by taking two face observations as opposed to single face observations incident angle error was almost completely removed with accuracy improving up to 5 times.
