Micromet's Radar Systems use a Transponder as an active target. It is usually placed at a fixed location at the end of a test straightaway. The test vehicle carries a Radar Transmitter that communicates only with the Transponder. When the test vehicle moves, changing the distance between the Radar and Transponder, the Radar uses the Doppler principle to develop a sequence of pulses. The pulse frequencies are used to measure vehicle speed and they are counted to measure distance traveled. This Radar Transponder method of measuring speed and distance is much more accurate and less interference prone, than methods used in police Doppler radars, where the test vehicle is the target.

One Radar Transmitter and one Transponder can be used to measure vehicle speed and distance traveled as the vehicle travels in essentially a straight line. Two Transponders and a two channel Radar can be used to measure the position and speed of a test vehicle as it moves in any direction in a designated test area. High sample rates permit recording the history of a moving vehicles position within a fraction of an inch.

Some applications of our radar systems include:

• Vehicle Speed vs. Time and Distance measurement
• Stopping distance during braking
• Vehicle drift measurement during straight line testing
• Measuring speed, position, and angle during high speed lane change maneuver
• Acceleration and coast down profiles
• Park backlash measurement
