Abstract

Aspects of the present invention relate to the stabilization of head-worn micro-Doppler antennas.

Claims

1. A head-worn micro-Doppler system, comprising:

a helmet mount adapted to attach to a helmet; and

a micro-Doppler antenna securely mounted on the helmet mount, wherein the micro-Doppler antenna is stabilized with respect to the environment such that the micro-Doppler antenna position is moved to compensate for helmet movements.

2. The head-worn micro-Doppler system of claim 1, wherein the micro-Doppler antenna is stabilized with a piezo-electric motor.

3. The head-worn micro-Doppler system of claim 2, wherein motions of the helmet mount are monitored with an inertial sensor and the inertial sensor outputs control signals to operate the piezo-electric motor.

4. The head-worn micro-Doppler system of claim 1, wherein an output from the micro-Doppler antenna is processed and presented as digital content in a see-through computer display.

5. The head-worn micro-Doppler system of claim 4, wherein the see-through computer display is mounted in a head-worn computer.
