Epsilon Lambda Electronics Corp

About Us

EPSILON LAMBDA ELECTRONICS CORP was founded in 1974 by Robert  M. Knox. Company focus is always on millimeter wave integrated circuit technology, subsystems and systems.  Product and technology applications are for low cost, short range radar and wideband communication systems.  Most radar products are based on FM-CW modulation for ranging and are provided with embedded software to operate the radar and provide data output for tracking detected objects, whether moving or fixed.  Other radar products rely on the Doppler principle to detect speed of moving objects.


Application focus for traffic control and vehicle detection markets offers products in the unlicensed band at 24GHz.  For example, a Traffic Control Radar detects vehicle location in range while providing instantaneous speed measurement.   A companion 24 GHz product Intersection Safety Radar also detects azimuth angle, allowing tracking of each vehicle by its lane location, range and speed for multiple vehicles approaching an intersection or operating on a highway.

Vehicle on-board obstacle detection for collision avoidance is facilitated by Epsilon Lambda Vehicle Obstacle Detector operating at 47 GHz which  detects vehicles by lane location, range and relative speed.  A similar capability is offered by a sensor operating at 77GHz.

Object detection radar is offered at upper millimeter frequency 94 GHz.  A recently introduced model provides 360 degree, three dimensional obstacle detection for use on robotic ground vehicles. The wide modulation bandwidth available at 94 GHz allows very high range resolution while operating with a small antenna.

The company offers a miniature Doppler speed sensor that can be used for temporary human location and navigation if GPS satellite tracking is temporarily blocked.  When mounted on a dismount soldier back pack, the battery powered ELGM91-1D sensor can be used to track movement.


Under contract from the US Navy, Epsilon Lambda is developing 60 GHz wireless network node technology as a replacement for avionics cables in future aircraft with benefits to reduce weight and increase usable payload space.  Ask us about CLIPAtm which will revolutionize future aircraft design.

A recently completed research contract for the National Institute of Justice was directed at development of 94 GHz electronically scanned radar for stand-off detection of concealed weapons or bombs carried by a criminal or terrorist.  Ask us about a better, faster way to screen airline passengers.

The company is conducting research for the US Air Force to employ dual mode sensor technology, radar plus electro-optical camera, for satellite awareness in the geo-centric communications satellite orbit.  Ask us about the next step to Space Based Space Awareness.

A research contract for the Naval Air Systems Command applies the Epsilon Lambda dual mode sensor technology to airborne refueling of unmanned air vehicles (UAV’s).  Ask us about AAR (Autonomous Airborne Refueling).
