Mathematical Absorber Reflection Suppression (MARS) for ...

Self-Comparison Measurements• Self-comparison technique often used to evaluate the effectsof error sources on the measurement results• Useful to establish a „truth model‟, or our best estimate ofthe „correct‟ measurement result• Use this for comparison to results derived with compromises inaccuracy in favor of reduced test time. For this, we use threesteps:1. take the data with minimal or controlled position errors (stop motion orslow scanning)2. average out range reflection and alignment errors with a redundantscanning technique3. apply NSI‟s Mathematical Absorber Reflection Suppression (MARS)technique• These three steps will help to derive the „true‟ antenna radiationpattern for use in subsequent self-comparison measurements toderive the effect of error sources.10
