Functional Description
The SCANTER 1002 Radar System is an integrated unit containing both the radar
transceiver, power supply, embedded computer and antenna with motor and
encoder. The system is enclosed in a radome and a sun cover, which provide envi-
ronmental protection and passive cooling.
The transceiver utilizes frequency modulation (chirping or frequency sweeping)
and pulse compression to increase the range resolution as well as the S/N (signal-
to-noise) ratio. This allows for transmission of long frequency-modulated chirps
with low peak power, and the ability of high range resolution and probability of
detection.
The system uses Digital Frequency Synthesis to generate chirps within the four fre-
quency bands, which can be selected by the application. The signal is generated
in the PC module, which contains the SCANTER 1002 transceiver processing sec-
tion. The receiver will automatically tune to the transmitted frequency bands and
pass the received signal to the PC Module which will sample the signal, demodu-
late it, perform pulse compression and post-processing. This will generate radar
video used for plot extraction and tracking.
