Research Institution
1An UWB data link is proposed to be added to an existing ANRO impulse radar sensor by creating a block orthogonal transmission scheme (e.g., pulse position modulation) where one of M equal-energy orthogonal signals is transmitted each pulse repetition period together with the radar main bang. Synchronization of the down-link data channel is accomplished by radiating a separate orthogonally polarized signal in coincidence with the main bang. It is shown how an existing miniaturized and solid state (proprietary) modulation/baseband transmitter, ideal for low-cost RPV application, can be modified directly to produce data rates as high as a 50K bits/sec; it is also shown how higher data rates can be achieved. The Phase I program is structured as a combined theoretical and experimental effort to determine concept feasibility. Techniques for LPI data transmission and a study of other synchronizing techniques, as well as the decoding of the data downlink by tunnel diode constant false alarm receiver channels are described. A laboratory experiment demonstrating the feasibility of a free space 10K bit/sec link is proposed under Phase I; expanded data rate capability will be examined during a Phase II program.
