Innovative
Technical Systems has designed a wide variety of custom target
generators for measuring the performance of microwave automotive speed
cameras. With models operating at 24 GHz and 34 GHz, our target
generators can simulate simple, single targets moving at a constant
speed, or more complex range-speed targets with dynamic motion.

The
ATG-9100 is an example of a laboratory-quality instrument that will
simulate complex target motion. Microwave signals from the speed camera
enter the instrument through an integrated antenna which is then
downconverted and digitized. Target simulation data is added to the
digitized signal to provide range and Doppler information. The modified
digital data is then converted back to an IF and upconverted to the
original microwave frequency of the speed camera and radiated back
through the antenna. Since the ATG-9100 can be phase-locked to an
external 10 MHz reference standard, this instrument is suitable for use
as a calibration standard for speed cameras.
Target data is
generated either through a Windows-based GUI control program, or can be
uploaded with an external data file. High speed communication is
provided via an Ethernet interface.

| Hand Held Target Generator |
|
For
simple Doppler target applications where a portable instrument is
needed, Innovative Technical Systems has developed hand-held generators
at both 24 GHz and 34 GHz. Simple constant-speed Doppler targets can be
simulated with variable speed, amplitude, and direction.

Doppler
signals can be generated from the internal signal source or from an
external waveform generator for more complex simulations. An integrated
antenna serves as both the receiving and transmitting aperture. These
highly portable instruments are conveniently powered from 12V sources,
allowing them to be used in the field with battery connections to
vehicles, or in the laboratory.
