    • Narrow virtual transmit pulses are synthesized by differencing long-duration, staggered pulse repetition interval (PRI) transmit pulses. PRI is staggered at an intermediate frequency IF. Echoes from virtual pulses form IF-modulated interference patterns with a reference wave. Samples of interference patterns are IF-filtered to produce high spatial resolution holographic data. PRI stagger can be very small, e.g., 1-ns, to produce a 1-ns virtual pulse from very long, staggered transmit pulses. Occupied Bandwidth (OBW) can be less than 10MHz due to long RF pulses needed for holography, while spatial resolution can be very high, corresponding to ultra-wideband (UWB) operation, due to short virtual pulses. X-Y antenna scanning can produce range-gated surface holograms from quadrature data. Multiple range gates can produce stacked-in-range holograms. Motion and vibration can be detected by changes in interference patterns within a range-gated zone.
    • 通过差分长持续时间,交错脉冲重复间隔(PRI)发射脉冲来合成窄的虚拟发射脉冲。 PRI在中频IF交错。 来自虚拟脉冲的回波形成具有参考波的IF调制干涉图案。 IF滤波器对干涉图样进行IF滤波,以产生高空间分辨率的全息数据。 PRI交错可以非常小,例如1ns,以从非常长的交错发射脉冲产生1ns虚拟脉冲。 占用带宽(OBW)由于全息所需的长RF脉冲而可能小于10MHz,而由于短虚拟脉冲,空间分辨率可能非常高,对应于超宽带(UWB)操作。 X-Y天线扫描可以从正交数据产生范围门控表面全息图。 多范围门可以产生堆积在范围内的全息图。 运动和振动可以通过范围选择区域内的干涉图案的变化来检测。
