MDR with thermal camera mounted on top

The MDR is designed for both land and seaside security. The radar does not rotate; rather, it has 3 or 4 discrete beams of energy that can be pointed in all directions. This solid-state system computes the average Doppler signatures of the environment and intruders. The Doppler signature of an intruder (person, or vessel, or vehicle) differs significantly from that of the environment. This ability to differentiate between the intruder and everything else permits the radar to remove unwanted signals for optimum performance against intruders. The radar comes with a mounting hole pattern on top for equipment (such as cameras). This radar is maintenance free for 2 years.

The table below shows the width of the beam of the radar at distances from the radar.

The MDR comes in 3 and 4 antenna models.  The antenna positions are adjustable and a variety of shapes are available at no extra charge.

Transmitted FrequencyX-Band, 9.25 GHz 
Peak Radiated Power  2 Watts
Average PowerMaximum 0.2 Watts
Antenna Beamwidth
  • 4 antennas with 7 degrees x 7 degrees (azimuth x elevation)  for 4- beam  models
  • 3 antennas with 7 degrees x 7 degrees & 1 antenna with 360 degrees for  3-beam models
  • Other antenna options are available (e.g.,  29 degrees and 48 degrees).  Larger antennas with narrower beams (e.g., 3 degrees) are available for outside mounting.
ScanningThe antennas are polled many times a second using electronic switching.
Scan RateEach antenna it monitored  every 1/10 of a second or less.
Bandwidth1-5 MHz   (selected via dip switches)
Pulse Repetition Frequency 4 kHz
