Abstract : This report documents the investigation of the uses of tactical radars and tropo-scatter communications, and the effect of siting errors on their mission performance. The mission most demanding of these equipments, in terms of accuracy requirements, is determined for tracking radars and 3-dimensional surveillance radars. Other missions of other radars are either similar or less stringent than those chosen to be representative. The blind bombing mission for the tracking radar and the fixed-point vectoring mission for the surveillance radar are selected as representing the most demanding missions. The effects of errors in siting the radars are then calculated to demonstrate the manner in which these errors affect the ability of the radar to perform its mission. Criteria are developed to show the degradation in mission performance as a function of the surveying capabilities of the subsystem. For the tracking mission, the criterion is a direct cost-effectiveness relationship comparing the cost of destroying a number of prescribed targets according to the precision of radar siting. For the surveillance mission, the criterion depicts numerically the degradation of radar performance due to siting errors from that which could be expected from a perfectly sited radar. Conclusions from these investigations point out the dominant role that radar alignment plays in radar capability degradation. (Author)
