    • Transmit multibeams insonify an object with multiple noncollinear transmit beams fired substantially simultaneously. The noncollinear beams are along different scan lines of same scan geometry, or they belong to scan lines of different scan geometries. One or more receive beams are formed in parallel in response to each of the noncollinear beams. The scan geometry and/or center frequency is varied between the noncollinear transmit beams of a transmit event. By scanning the transmit multibeam, and varying the scan geometry and/or frequency between the noncollinear transmit beams of a transmit event, multiple component images are generated for compounding. The component images are scan-converted (if scan geometries are different), weighted and combined after envelope detection.
    • 发射多波束使多个基本同时发射的非共线发射波束对象物体失真。 非共线光束沿相同扫描几何的不同扫描线,或者它们属于不同扫描几何形状的扫描线。 一个或多个接收波束响应于每个非共线波束平行地形成。 扫描几何和/或中心频率在发射事件的非共线发射波束之间变化。 通过扫描发射多波束,并改变发射事件的非共线发射波束之间的扫描几何形状和/或频率,生成多个分量图像进行复合。 组件图像进行扫描转换(如果扫描几何不同),在包络检测后加权和组合。
