Which of the following is not a required fact of RADAR used in court?

In the context of RADAR use in court, certain facts must be established to validate the reliability and accuracy of the evidence obtained from RADAR systems. The calibration of the instrument, certification of the operator, and adherence to established procedures are all critical elements that ensure the integrity of the data being presented in court.

Calibrating the instrument ensures that it provides accurate measurements, which is fundamental in establishing the reliability of the evidence. Certification of the operator demonstrates that the individual has met the necessary training requirements and understands how to operate the equipment correctly, further ensuring that the data collected is valid. Following procedures is essential for maintaining consistency and accuracy in the use of the equipment during data collection.

However, the necessity for the operator to be trained specifically in physics is not a mandated requirement for the admissibility of RADAR evidence in court. While a foundational understanding of the principles behind RADAR could be beneficial, it is not a specified prerequisite for the operator's qualifications or for the evidence used in judicial proceedings. This distinction highlights that the critical concerns lie mainly in the technical operation and management of the RADAR equipment rather than a deeper academic understanding of physics.
