Introduction
Congratulations on your purchase of the Houston Radar Ranging PD420 radar. This state
of the art 24GHz K-band microwave
frequency modulated continuous wave
(
FMCW
)
radar is specifically designed for the license free battery and solar operated presence
detection market. Unlike regular Doppler radars, FMCW radars are capable of measuring
range and detecting stationary targets.
Typical applications include multi-lane traffic counters, ground loop replacement, mid-
block detectors, vehicle activated signals and intrusion detectors.
Utilizing high performance, ultra-low power DSP (Digital Signal Processing) technology
and microwave components based on a planar patch array antenna with integrated low
power PHEMT oscillator, you will find that this high quality product meets your exacting
standards for performance and reliability.
Some of the highlights of this product include:
World’s smallest and lowest power usage ranging FMCW radar. At 0.35 Watts PD420 requires 10 to 20
times less power than competing products. Well suited for solar and battery powered installations.
Up to 250ft detection range
Simultaneously detects, tracks and reports up to six individual targets.
Six user-configurable lanes allow assignment of targets to specific lanes.
Six hardware trigger outputs can be mapped to any combination of lanes.
Unmatched range resolution down to 0.25 inch (0.63cm)

.
Highway and intersection optimized modes allow wide variety of applications.
Companion Windows application provides intuitive GUI to set all configuration parameters and display
real time plots of the targets, lane by lane counts and accumulated count histograms.
Firmware “boot loader” allows for field upgrading of the firmware.
100% built-in self-test for high confidence.
IO break-out board available for quick evaluation.
Built-in statistics storage memory for stand-alone lane-by-lane count gathering.
Software Development Kit (SDK) with code examples for custom application development.
Full industrial temperature range. Potted for high reliability.
FCC pre-approved with CE mark.
The PD420 is not just a “front end”, rather it is a complete radar with on-board
signal processing to determine range to multiple targets and application
algorithms to enable lane-by-lane counting and storage, presence detection,
occupancy measurement and other functionality as described below.
