The relative range rate error obtained by TPOGL is small most of the time, but it diverges at the end of the guidance because the accurate value of the relative range rate approaches infinity.
The range rate relative to the receiving station is
The target being observed will be offset from 0 Hz by a frequency [f.sub.d], which is proportional to twice the target's range rate divided by the radar wavelength [Lambda].
The radar must be able to track the maximum rate of change of the target range (i.e., the target moving directly toward or away from the radar), and to change its range tracking rate at the maximum rate of change of the range rate (i.e., the range acceleration).
At an absolute minimum, forward looking sensors must determine range and range rate. Angle information is not absolutely necessary and many single beam systems have been shown to be adequate for intelligent cruise control and collision warning.
* Pulse repetition frequency: low (LPRF), medium (MPRF) and high (HPRF); PRF designations usually apply to PD radar, where LPRF is unambiguous in range, HPRF is unambiguous in range rate (Doppler), and MPRF is ambiguous in both range and Doppler
