Abstract: Atomic clocks (at both the receiver and emitter) are used to obfuscate the location of the receiver by providing a different mechanism to synchronize (other than the direct reception). Using this approach, there is no need for the emitter to emit directly to the receiver; only the reflection is necessary, and therefore, the location of the receiver (or receivers) is better obfuscated. Phased antenna arrays are used in RADAR for a variety of applications, including steering of beams and increasing the “aperture” of the antenna for Synthetic Aperture Radar (SAR). The relative position of the emitters is known by means of using a Navigation unit. The beam-steering phase shifts are dynamically computed using the position of the emitters, and the atomic clock is used to synchronize the phase shifts.
