INTRODUCTION
This manual will discuss the installation and operation of Preco’s PV2000 Time Domain
Radar.
General radar and electro-magnetics theory will be left for the reader to pursue elsewhere.
INSTALLATION
The radar was designed to be mounted perpindicular to the ground at a height of 3 feet
(ground to center of radar). Mount radar at the rear of the vehicle, in the center.
If radar must be mounted at a height of less than 2.25 feet, then radar unit must be tilted
Up aprox 5 degrees, to keep the ground from being detected. If radar is mounted at
greater than 4 feet, then radar can be tilted down aprox. 5 degrees to avoid missing short
Targets within the range.
Connect the two conductor dc power connector to a dc supply of 9.6v-28volts.
Connect the round connector on radar sensor to the extention cable that goes up to the
cab of the vehicle, and connect LED box to extension cable.
OPERATION
The radar is designed to detect objects up to 8 meters(26.25 ft). The eight lights indicate
How far target is from radar unit. When 1 light is on, a target has just entered the
detection zone at 8meters away. When all 8 lights are on the target is within 1 meter of
The radar sensor. The audible indicator also beeps faster as the target approaches.
The radar was designed to meet SAE J1741, see spec. for zone parameters.
The PV2000 has a detection zone that resembles a pear, see zone pattern plot.
The vertical pattern is aprox. 20 degrees thruout the range and the horizontal is about 150
degrees at 0.5 meters, and about 45 degrees at 26 feet.
