Six-port Reflectometer with Kalman Filter Processing of Sensor Signals

In modern microwave measurements the six-port reflectometers and receivers are used in telecommunications, radiolocation, medicine, Internet of things. The signal processing is based on the algorithms and models that using the redundant information and is aimed at accuracy improving and uncertainty reducing. The Kalman filter is proven to be helpful in signals with errors processing. There was proposed a finite state machine (FSM) with such states as prediction and update for Kalman filter algorithm and its simulation with the help of field programmable gate array (FPGA).
