![]() ![]() Such FPGA switching circuitry may have a peak-to-peak jitter as high as 150 ps. The radar transmission trigger and pulse repetition frequency (PRF) control lines are generally digitally driven (e.g., field-programmable gate array (FPGA)). Further, the local oscillator carrier is often digitally synthesized, which sets the lower phase noise and spurious limits along with the smallest possible frequency increment. Thus, this RF path delay requires continuous calibration to achieve sub-nanosecond timing. Additionally, this delay may drift over the lifetime of the hardware, or due to temperature and internal platform power line variations. Depending on the RF architecture, this delay may vary by many nanoseconds. Moreover, the propagation delay from antenna feed to frequency sampling often changes depending on the selected radio frequency (RF) pathway, attenuation or gain, and frequency band. In cases where exploiting bistatic SAR using transmitters of opportunity locating objects of interest in operational theaters without drawing the attention of hostile forces, the limits on time and frequency synchronization may well be set by the radar hardware rather than the method of time transfer. However, much could be gained by designing these subsystems from a multistatic system’s perspective. These problems are often approached monolithically and from a monostatic point of view. Simple one-way, or standard two-way, time transfer between flying clocks will completely break down because of the time-of-flight variations and Doppler shifts associated with the strongly time-varying link distances. Moreover, time errors translate to range errors, and phase and frequency errors negatively affect the Doppler processing and phase coherence. The stringency of this synchronization requirement tightens with increasing bandwidths and carrier frequencies. OBJECTIVE: Develop and demonstrate an adaptive distributed time, frequency, and phase synchronization system having a clock capable of achieving a stability less than 1E-15/sqrt(tau) with flicker floor less than 1E-17 with a 1E-16 long-term stability for a multistatic radar network.ĭESCRIPTION: There is a Synthetic Aperture Radar (SAR) network requirement for a precise space-time synchronization system.
