Apparatus and process for remote certification of doppler radar speed measuring devices
First Claim
1. A self-contained, multi-function test and measurement apparatus for use with a Doppler effect microwave frequency radar gun, comprising:
- a) internal control means for selecting and directing a plurality of test and measurement functions;
b) means, electrically connected to said internal control means, for performing a frequency measurement of a microwave signal generated by said radar gun;
c) means, electrically connected to said internal control means, for performing a microwave power density measurement of said signal; and
d) means, electrically connected to said internal control means, for performing a speed simulation test of said radar gun;
whereby at least one of said plurality of test and measurement functions is selectively performed on said radar gun as directed by said internal control means.

Abstract
A self-contained, single-unit test and calibration unit for Doppler-effect speed measurement devices (radar guns, etc.) is provided. The inventive unit is capable of performing manual, semi-automatic and automatic measurements on radar guns insuring no "missed" steps in the certification process. The unit is optionally supported by a general-purpose, digital computer such as a "PC" which may, in turn, be linked to a remote facility via modem or similar communication strategy. Either a local or a remote computer may oversee the test, calibration and certification processes. The inventive unit allows for fast and accurate certification of radar guns in the field by operators of only minimal technical skill thereby saving expense and time as radar guns no longer must be shipped to a remote certification facility.
