    Abstract: A precision timing generator (415, figure 4) includes a combiner (412) that provides a timing signal by combining a coarse timing signal (428) and a fine timing signal (429) derived from a phase-shifted sinusoidal signal (508) that has a desired phase shift. The coarse timing generator (404) generates the coarse timing signal from a clock signal (416) and a timing command input (420). The fine timing generator (408) includes a sinusoidal-signal generator (504) that receives the clock signal and generates a sinusoidal signal. The fine timing generator (408) also includes a phase shifter (508) that receives the sinusoidal signal and the timing command (420) input and shifts the phase of the sinusoidal signal based on the timing input to generate the phase shifted sinusoidal signal.

    Abstract: A method and system for applying delay codes to pulse train signals (10 and 12) is provided. The delay codes vary the time offset (X) between asynchronous pulse train signals (10 and 12) to eliminate persistence of pulse coincidences. The pulse train signal may comprise a repeating pulse train. The delay codes specify delays between individual pulse trains or some number of pulse trains. The delay codes result in averaging of pulse coincidences between the pulse train signals (10 and 12) over time. Additionally, the delay codes may be generated using a pseudorandom code generation technique.

    Abstract: A method and system for receiving time spaced signals transmitted in accordance with a time layout is provided. The time spaced signals convey an intelligent signal. The time spaced signals are received at an antenna. Once received, the time spaced signals can be coherently detected. Coherent detection may be accomplished by correlating (1310) the received signals with a template signal (1312). The detection process can also include integration (1314) of the received signals. The coherently detected signals are then contributed to a plurality of intermediate signals based on an interleaving order (1308), which may be predetermined or specified by an interleaving code. Each of the plurality of intermediate signals can then be separately integrated (1316), for example to produce bits of data. The bits of data are ordered to produce the at least one intellingence signal based on a bit order, which may be predetermined or specified by a bit ordering code (1322).

    Abstract: A system and method of implementing precision time delays that provides important and novel improvements over prior techniques of implementing time delays by utilizing a new strategy for selecting the values in the sine and cosine lookup tables. Sine and cosine values which result in non-uniform amplitudes enable increased overall accuracy with fewer bits communicated from the look-up tables to the analogue portion of the system. Further, herein is provided the addition of a variable amplitude threshold crossing capability following the combining of the sine and cosine signals. The time delay accuracy of the resulting phase and amplitude hybrid system can be improved either by increasing the number of bits in the sine/cosine phase management section or by increasing the number of bits in the amplitude section. There is provided herein an optimum strategy for choosing the number of bits used in the phase and amplitude sections for the best overall delay accuracy with the fewest overall control bits.
