Kustom Signals Inc DRU 用户手册

1.  UNIT DESCRIPTION - Kustom Signals, Inc. Directional Radar Unit (DRU) is a 

one piece, battery powered speed monitoring doppler radar device that can 
discriminate vehicle direction.  The transmitter, receiver and antenna are integral. 
The receiver is a two channel I/Q quadrature output.   The unit transmits in K 
band at 24.150 GHz +/- .1GHZ.  The transmitter is a Gunn diode cavity stabilized 
Continuous Wave oscillator.  All received signals are digitally processed and 
converted to RS232 format.  Data from the DRU is digitized vehicle speed and 
direction can be received by any peripheral capable of receiving and processing 
RS232 data.  

 

2.  INTENDED PURPOSE – The DRU is designed to be used for monitoring and 

data logging vehicle speed.  These data are then used to provide real time visual 
speed prompts for motorists and historical speed and direction data for statistical 
studies.  The DRU is to be used only in stationary applications as it is not capable 
of processing data while on a moving platform 

 

3.  SETUP – The DRU is intended for use in the Kustom Signals, Inc. speed 

monitoring awareness radar trailers.  DC power is supplied to the DRU by the 
trailers onboard batteries.  When power is applied operation is automatic.  All 
usage is stationary
