Introduction

JJF1002 "national verification procedures write rules", JJF1001 "common measurement terms and definitions" JJF1059.1 "Evaluation and Expression of Uncertainty in Measurement" basic Regulation constitute series support this protocol revision Fan. The main reference JJF1335-2012 "fixed angle radar speedometer type evaluation framework", JJG 1074-2012 "Motor vehicle laser gun" and other technical specifications.

This procedure is a revised version of JJG 528-2004. Compared with JJG 528-2004, in addition to editorial revision Outside the main technical changes are as follows.

--- Clear the order applies to mobile vehicle radar gun (see 1);

--- Canceled subsequent assays test site speed error;

--- Increased in real traffic situation to normal with the completion of the field test object vehicle speed error detection Given method (see 7.3.4);

--- Increased under Appendix A complete site's traffic speed error status test sample.

The previous versions of this Recommendation published case.

--- JJG 528-2004 "motor vehicle radar gun."

--- JJG 528-1988 "hand-held radar gun." Mobile vehicle radar gun verification procedures

1 Scope

The order applies to the application of the principle of the Doppler effect to measure the speed of a motor vehicle with mobile radar vehicle Speedometer initial verification, use and subsequent verification check.

4 Overview

Mobile vehicle radar gun can be placed on both sides of the road users' needs, based on the principle of the Doppler effect the detection area with the vehicle running speed of real-time values, automatic measurement.

Mobile vehicle radar gun typically comprises radar antenna, a signal processing unit and the speed of the display unit, for Motor vehicle with automatic recording of images and other relevant information should be equipped with speedometer image recording apparatus.
