Abstract
An optical acoustic charge transport (ACT) device provides a variable and continuous delay for RF signals. Received RF signals are converted to light and focused onto an optical ACT device. The continous delay is utilized to generate a false radar return.
Claims8
A false return signal apparatus, comprising:
- receiver means for receiving radar signals and for generating light responsive to the received radar signals;
- deflector means for variably deflecting the light across a predetermined area;
- and
- an acoustic charge transport device positioned in the predetermined area and having an output connected to provide a false return signal responsive to the light received from the deflector means.

A false return signal apparatus, further characterized as comprising:
- receiver means for receiving radar signals and for generating light responsive to the received radar signals;
- a Bragg cell positioned to receive the light and to deflect the light into at least one light beam across a predetermined area;
- a lens positioned to receive light from the Bragg cell and to focus the received light into at least one light spot within the predetermined area;
- and
- an optical acoustic charge transport device having a light sensitive channel plate positioned in the predetermined area and having an output connected to provide a false return signal responsive to light received from the lens.
