The problem of primary information indication is considered for the case of multi-functional radar maintenance workstation. Indication is proposed for monitoring radar primary information when multi-functional radar performs regular surveillance or target tracking. Primary information analysis allows understanding the reasons of false plots and false tracks occurrence, and the reasons of target track losses. This article proposes graphical user interface of maintenance workstation. When radar performs regular surveillance, proposed interface allows the selection probing of angular direction, in which false plots are occurred, and then the monitoring of primary information for the selected direction. When radar performs target tracking, proposed interface allows the selection of a desired target on the display and the monitoring of primary information for the selected target.
