The use of microwave noise from the Sun for on-line verifying azimuth alignment of surveillance radars

Radar system cannot operate standalone. Information about detected targets should be send to command and control system. The C2 systems often realize fusion of data coming from bigger number of radars. General problem in data fusion process is quality of received radar data. The radar data quality strongly depends on radar systems calibration and adjustment. One of the source of adjustment errors is azimuth alignment of the radar. In the paper the use of microwave noise from the Sun for on-line verifying azimuth alignment of surveillance radars will be discussed. The real results of radar alignment, advantages and disadvantages will be presented.
