Utvärdering av individuella skillnader hos mikrovågssensorer

Sammanfattning: The purpose of this study is to investigate if individual differences exists between microwave sensors from the same manufacturer and to find which variables of the microwave sensors that can be the reason for those individual differences. To investigate this, an experiment environment was made to gather data from microwave sensors in a repetitive way. This experiment environment was used in three different experiments where individual differences, radiation pattern and noise were measured. As a base for the experiments a literature review was made to find variables that could affect the individual differences. The study shows that individual differences on signal strength can be found on microwave sensors of the type MDU2000 from Microwave solutions. Also, the radiation pattern at higher angles can differentiate. The frequency from the microwave sensors at lower speeds shows no significant difference individually. This study contributes to increased knowledge about individual differences on microwave sensors of the type MDU2000. Results from this study can be used as a recommendation to suitable applications. As both resources and time have been limited during this thesis, the study was limited to only perform tests on microwave sensors of the type doppler radar. Another limit to the study is to only do tests at lower speeds i.e. a maximum speed of 5km/h.
