Development and Manufacture

Model No. XRD

KEYCOM develops various radars for versatile applications based on its knowledge and expertise on
millimeter wave and microwave technologies. KEYCOM’s product line of radars includes
Radar Test Systems (RTS) to evaluate distance accuracy or output, Radar Alignment Systems (RAS) to
help you adjust the alignment of radars, and Radar Cross Section (RCS) measurement systems to
measure RCS of such radar targets as aircraft, ships and automobiles.

1. Radar system development and manufacture

Radar Systems / Millimeter Wave Radar / Micro Wave Radar
Development and Manufacture		   Standard Radar Targets (Sphere or Triangular Trihedral)
MRS01   RES02
KEYCOM develops and manufactures various radars, radar systems and altimeters that will meet your specific requests, for quantity as small as one. Our experts in high frequency engineering design them by using our original analysis tool that is comprised of our expertise accumulated over the last 20 years. The designs are then verified based on our prototype models or high-performance 3 dimensional electromagnetic analysis tool.
In addition to on-board radars for automobiles, KEYCOM develops and manufactures such millimeter wave and micro wave radars as 94GHz radar, FMCW type weather radar, 76GHz band standard radar, pulse Doppler radar, 24GHz edge radar, and phased array radar for aircraft.		   -Spherical type
　　No directionality, simple operation.
-Triangular trihedral type(cornerreflector)
　　Wide directionality
　　Laser pointer installable (option)

2. Radars

Imaging Radar System   Prototype Automobile Radars
RCS04   RDC01
*RCS (Radar Cross Section) measurement
- Creates images of reflection signals from targeted objects that actual collision avoidance radars are intended to receive, nearly real-time.
*Intruder monitoring, moving target monitoring (whole surrounding monitoring option available)
*Level gauge
*Fluid flow analysis		   KEYCOM develops and manufactures prototype automobile radars, selectable either 76GHz or 24GHz, FMCW or pulse radar.
Customization of data output is optionally available.
Because it is a specified low power device, no radiotelephone license or certification is necessary.
     
Area Monitoring Radar Series    
RDE    
KEYCOM develops and manufactures different area monitoring radars. You can select 60GHz or 24 GHz, and FMCW or pulse radar as the technology to be used.
We provide custom data output tailored to your system specification. 		   

3. Synthetic aperture radar

Synthetic Aperture Radar (Natural Disaster Prognostication, Long Range Displacement Observation System, FM-CW)    
RAD01    
KEYCOM’s synthetic aperture radar RAD01 watches for signs of disasters such as a fracture of a bank, a rock fall, collapse of a tunnel, a landslide, and so on, for 24 hours a day.
It detects a displacement as small as 0.1mm and alarms.		    

4. FMCW radar

Synthetic Aperture Radar (Natural Disaster Prognostication, Long Range Displacement Observation System, FM-CW)   FMCW Radar Transmitter / Receiver
RAD01   PBR71
KEYCOM’s synthetic aperture radar RAD01 watches for signs of disasters such as a fracture of a bank, a rock fall, collapse of a tunnel, a landslide, and so on, for 24 hours a day.
It detects a displacement as small as 0.1mm and alarms.		   KEYCOM develops and manufactures various radars, radar systems and altimeters that will meet your specific requests.
     
FMCW Meteorological Radar Aerial   94GHz FMCW-Type Weather Radar
PBR72   RAD76
1.The reflective mirror attached to the flat frame ensures that the directionality of reception and transmission coincide.
2.The transmission and reception antennas are separated, ensuring that the received and the transmitted signals are isolated from each other.
3.Snow does not lie on the radome because it is slanted.
4.The radome can be easily removed. 		  • Millimeter-Wave (94GHz band) weather radar.
• Capable of observing the development of clouds.
• The FMCW method enables highly sensitive observation with low power.
• Observation is possible with pyramid-shaped, fan-shaped, or fixed beam.

5. Pulse radar

76GHz Standard Radar (Pulse Radar)   Pulse Doppler Radar
PAR02   PAR73
1. Antenna’s directional angle continuously variable 10° to 2° through dielectric lens antenna.
2. Its log amplifier enables highly accurate receiving level measurement, and converts it to DC voltage.
3. Distance accuracy: ±15cm.
4. Because it is a specified low power device, no radio license or certification necessary. 		  1. Because it is a specified low power radar, no radio license or certification necessary.
2. Displays received waveform semi-realtime
3. Detailed data analysis is possible as the received signals can be stored in CSV format.
     
24 GHz Edge Radar (Pulse Radar)   94GHz Pulse-Type High-Sensitivity Weather Radar
PAR01   RAD75
This radar performs highly precise distance measurement in the range between 50cm and 35m.
Because it is a specified low power radar, no radio license or certification necessary.
Network operation allows high extensibility and remote monitoring. 		 
  • Used for the checkup of the cloud radar mounted on satellite EarthCARE (Earth Clouds,
    Aerosols, and Radiation Explorer) (The observation sensitivity is 10 dB-higher, or further higher than the radar mounted on satellite EarthCARE.).
  • This instrument is a millimeter-wave (94 GHz band) weather radar. It can penetrate fog and smoke, which is diffi cult by optical methods.
  • Low time side-lobe.

6. Phased-Array Radar

Phased-Array Radar   Receiver for 94GHz Phased-Array-Type Weather Radar
RAD74   RAD73
The azimuth is swept mechanically and the elevation is swept electronically.
The antenna is slot array type.		  
  • Used for the checkup of the cloud radar mounted on satellite EarthCARE (Earth Clouds, Aerosols, and Radiation Explorer).
  • Confi gurable array antenna (e.g., zigzag confi guration).
  • Phased array receiver for a Millimeter-Wave (94 GHz band) weather radar.
  • The grating lobe of the electron scanning direction can be mitigated by changing the confi guration.
  • The gain and phase shifting are accurately adjusted for each RF receiver module so that each RF module does not have a phase shift.
    Therefore, the phase shifter is installed for each fan beam (linear array).
