Error sources applicable to precision trajectory radar calibration

The purpose of this document is to identify possible sources of error in measurements by land-based monopulse and phased array radar systems. Recognition of these error sources will be useful in several ways. Operations personnel will be able to more easily recognize deficiencies in calibration procedures and utilize existing procedures more proficiently to minimize calibration errors. System design/procurement engineers will be reminded of potential error sources enabling more realistic design and acceptance specifications to be written for future equipments. Planning groups will be able to identify the limitations which affect the applications of the radar. Those engaged in operations engineering may utilize this document as an aid in identifying those modifications which would be more beneficial in improving the performance or accuracy of operational radar systems. In addition, data reduction personnel will be aided in the evaluation of the total effects of current and/or proposed data reduction and analysis techniques of radar data by recognizing the source and in some cases the magnitude of system bias errors.
