Radar and associated projects
- Investigation
into ranging and location of small low power transponders
using VHF spread-spectrum modulation technique
- Developed
a low power homodyne radar for detection of vibration at
a distance
- Developed
an RF probing system for the remote measurement of torque
in a spinning shaft
- Microwave
synthesised tracking source for a high altitude, X band
radar jammer operating over extreme temperature range.
- X-band
active radar targets for airborne and marine applications
- Experimental
low cost compact radar altimeter at 4.3 GHz
Initial
CAD drawing
Prototype
radar target, filter designed using Wavecon PARFIL,
The
device uses a slotted waveguide array to give a horizontally
polarised
omni
response (see the antenna page). The prototype PCBs were made by
PCB train on Taconic RF35 laminate.
Field-testing
a target on Hayling Island, near Portsmouth harbour
Prototype
SAW interrogator for remote torque measurement, 50 kHz bandwidth
Prototype homodyne
radar / altimeter, aerials by European Antennas Ltd
(300 mW transmitter)
