Seeking Radar Absorbent Coating for High Speed Applications

Multi-Frequency Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. It does this by bouncing a microwave signal off a desired target and analyzing how the object's motion has altered the frequency of the returned signal. This variation gives direct and highly accurate measurements of the radial component of a target's velocity relative to the radar.

We are seeking to coat objects so they are undetectable by these radar systems. The typical velocities of these objects will be 100 to 950 m/s.
