Measurement Error Correlation in Processing of Overlapping Blocks in FMCW Radar

Abstract

The paper investigates measurement error correlation caused by the processing of overlapping blocks in FMCW (Frequency-Modulated Continuous-Wave) radar. The problem is analyzed theoretically by discussing the impact of measurement error correlation on tracking and mathematical evaluation of the effect. The results are confronted with simulation and data from an real experiment. The paper describes predicting measurement error correlation to allow for proper addressing the issue in the tracking subsystem.
