Page 6: Introduction
Some of the highlights of this product include: World’s smallest and lowest power usage ranging FMCW radar. At 0.18 Watts PD300 requires 10 to 20 times less power than competing products. Well suited for solar and battery powered installations. -
Page 7: Principle Of Operation
The radar detection zone has an oval shape and is defined by the beam cone (38ºx45º for PD300, 20ºx60º for PD310) and incident angle to the road surface. Note that the beam does not cutoff abruptly at the boundary of the detection zone but rather gradually tapers off. - Page 8 Also note that the radar beam is wider in one direction and the fundamental operation of the radar is not affected by the mounting orientation. This fact may be used to either widen or narrow the detection zone in the direction that matters. For a wider horizontal detection zone, mount the radar with the wider beam in the horizontal direction.

Page 9: Radar Pointing
Radar Pointing The radar beam may be pointed across the traffic at 90º to the road or in line with traffic into incoming or outgoing traffic. Pointing the radar at an angle substantially different from 90º or 0º is not recommended because the signal strength is severely reduced. The industry refers to pointing the radar at 90º... -
Page 10: Choosing A Ctc Value
You MUST issue the “Initialize Clutter” command via the provided GUI after you have setup the radar in the intended location. You MUST reissue this command if you change the operating mode of the radar, as the clutter map will be considerably different. You MUST reissue this command after you adjust the radar pointing, height or angle on the road. -
Page 11: Operating Modes
Operating Modes The radar can be configured to function in different operating modes that are optimized for various applications. Current firmware supports two pre-programmed modes: “Highway” and “Intersection”. For the best performance an appropriate mode should be selected by the user depending on their intended application. Highway mode (side firing only) To take advantage of this mode the radar must be deployed in a side firing installation so that it looks across the road and NOT directly into incoming or receding traffic. -
Page 12: User Configurable Detection Lanes
An external controller communicates with the radar via the Houston Radar Binary protocol. The same protocol is used to communicate to all radars (Doppler and FMCW) produced by Houston Radar. Please contact us for a “C”... -
Page 13: Historical Lane Counts
When radars are located close to each other and point in the same direction they may interfere with each other unless their frequency sweeps are synchronized. PD300/PD310 provide facility to synchronize two or more radars in a “single master, one or more slaves”... -
Page 14: Radar Configuration And Data Variables
Configuration parameters are stored in persistent variables. The easiest way to configure the radar is to use supplied Houston Radar Windows Configuration Utility. It will present you with a set of easy to understand configuration options. Once the user makes his selection, the Configuration Utility converts user specified options into a set of configuration variables and stores them in the radar. -
Page 15: Internal Clock
Internal Clock The radar has a built in clock/calendar function. This is used to keep the time for time stamping historical records saved by the Advanced In-Radar traffic statistics collection feature. Because the radar is potted it does not feature a built-in clock backup battery. The power must remain on for the clock to keep time. -
Page 16: Streaming Ascii Data
Streaming ASCII Data In instances where a simplified interface is desired and a user only needs to know only counts and/or occupancy indicators on periodic basis, the radar may be configured to stream counts per lane and occupancy indicators per lane every TA seconds. TA is a configuration variable that can be set to desired data output interval in seconds. -
Page 17: Radar Mounting
Radar Mounting Beam pattern and enclosure PD300 and PD310 radars feature asymmetric beam patterns and can be supplied in either open frame or weatherproof version. Your intended application will determine the choice of the case type, beam pattern and beam rotation. - Page 18 To achieve wide vertical beam angle, the PD300-DFT should be mounted such that the text “Houston Radar” on the face of the unit is horizontal. This orientation is typically used in the “Highway mode” where you are measuring per- lane count and occupancy while the radar is mounted at the side of the road and fires across the lanes at 90º...

Page 19: Mounting The Pd310 (20X60Deg Beam Angle)
To achieve wide vertical beam angle, the PD310-DFT should be mounted such that the text “Houston Radar” on the face of the unit is vertical. This orientation is typically used in the “Highway mode” where you are measuring per- lane count and occupancy while the radar is mounted at the side of the road and fires across the lanes at 90º... -
Page 20: Mounting Bracket
Mounting Bracket Mounting bracket should allow for sufficient adjustment of the radar pointing angle and height. At the very minimum some degree of adjustment for the vertical angle should be provided. The user must perform a “boresight” check to validate that the radar beam is pointed correctly.
