Thanks to Cannoneer #4 for sending me this, and this is an excellent addition to The Defense of Farms and Ranches post. The other thing I like about articles like this, is it highlights exactly what works and what doesn’t work out there. What these ranchers are dealing with, is a daily issue that has been going on for years. An individual protecting his land will come across a multitude of ideas, and try everything under the sun to get a job done. They will also be pushing that equipment’s lifespan to the limits, and all of this information about the products longevity and usefulness is vital to other end users and to the company that made it.
Personally, I have not used this product, so I cannot endorse it. I also have no connection to the company, and this just came across my desk as something that was interesting. If any FJ readers have experience with this equipment, I am sure the rest of the readership would be interested to hear about that-good or bad. –Matt

Calif. Ranchers Wield British Radar to Detect Illegal Border Crossers
December 2009
By Grace V. Jean
LONDON — Frustrated by trespassers attempting to cross into the United States illegally, ranch owners in southern California have purchased a British radar in an effort to protect their property and to help Border Patrol agents nab more intruders.
The Blighter B202 Radar, developed by Plextek Ltd., an electronics and communications design consultancy based near Cambridge, U.K., detects people walking or crawling through the rocky, hilly landscape from four kilometers away, says Nicholas Booth, manager of Blighter sales and marketing.
The man-portable, scanning radar is mounted on a tripod and runs on rechargeable lithium ion batteries. It has a 20-degree wide vertical elevation beam that permits the detection of targets in the distance as well as up close.
“You can see people walking up and down the mountain and on the plains at the same time,” says Booth.
Traditional radars would require tilting to cover the same area.
When the Blighter radar detects movement, the target is displayed on a map with information on its exact location, size and speed. Other elements of the ranchers’ surveillance system, including day/night cameras, acoustic and warning devices and unattended ground sensors, help to confirm whether the target is human. But the devices are subject to environmental factors that may hinder their effectiveness.
“We regularly experience early morning coastal fog that renders our [infrared] cameras useless,” one of the ranch owners says in a company press release. “Of all the surveillance equipment we use here, the Blighter radar has proven itself to be the most solid, reliable performer of all.”
The radar has been updated with new software, called BlighterTrack, that allows the operator to see the path traveled by the intruder and also filters out false detections triggered by wildlife and other natural occurrences.
Plextek also has developed a technology called Vortex Fast-Scan that accelerates the radars’ scanning speed from once every five seconds to once per second. Revisiting targets every second gives better accuracy, says Booth.
“We have reported many groups of aliens based on Blighter’s alarms alone with which the Border Patrol has made apprehensions,” a rancher says.
The radar system is remotely accessed via the Internet so that the ranchers can control and monitor the system from their homes.
Plextek’s radars are employed mostly by the U.K. Ministry of Defence. But the company is looking to break into the U.S. government market.
“I’m quite hopeful that with the positive feedback from the border guards that we’ll get noticed,” says Booth.
