Radar Height Bias Estimation for a Ground-Based Radar Using an Aircraft Altimeter as a Standard of Reference
Abstract
Buyers of modern Air Defense Radars usually specify bounds for the total root-mean-square (rms) errors of range, azimuth and height. These errors have bias and random (jitter and thermal) components which appear as summed variances. With a colocated precision track radar with known errors much smaller than the radar under test, the total rms error is established in a straightforward manner. For test sites without such a standard, the problem is more difficult. Such is the case for the majority of buyers of the GE-5923-D Air defense Radar. However, a standardized approach to this problem has emerged in which the bias and random errors are characterized separately, without the need for a colocated precision track radar. A method for making unbiased estimates of the variance of random errors has been developed and a paper is currently in preparation. This paper deals entirely with the characterization of radar height bias errors.
