CRANE-102251
Current methods are inadequate at producing focused energy at a specified location in space. Different portions of the signal can be produced from antennas in physically different locations, all focused to recreate the original waveform at the desired location.

Naval Surface Warfare Center, Crane Division (NSWC Crane), has developed and patented a method and apparatus to realize an input waveform using wavelet processing and reconstruction via separated antenna array systems having different beam paths and different frequency components, which can include phased array transmitters to recreate the input waveform. This technology has the capability of creating a variety of arbitrary signals using acoustics, radio frequency, laser, ultrasonic, electrical, or any other medium to which signal processing techniques can be utilized. Arbitrary signal for communication, interrogative, identification, disruption, jamming, deception, etc., can be created at a specified location such as the path of an oncoming threat. In addition, this technology has the ability to protect signal interception and also to guide away unauthorized users.

Advantages:
-Guide away unauthorized users
-Protect signals from interception

Potential applications:
-Communication
-Electronic Systems
-Medical
-Entertainment
-Security
