  1. A doppler radar only measures the component of the velocity in the line of sight, the so - called radial velocity

    因為多普勒雷達探測到的僅僅是風矢量在徑向上的分量。
  2. High frequency surface - wave radar ( hfswr ) utilizes the surface - wave mode of vertical polarization electromagnetic wave propagation over sea water to detect targets of ships and aircrafts at distance beyond the line of sight

    高頻地波雷達（ hfswr ）依靠高頻垂直極化電磁波沿海洋表面繞射傳播的機理，實現對海面艦船目標和低空飛行目標的超視距探測。
  3. The airborne isar imaging of ship target depends on the ship ’ s rotation relative to the radar line of sight ( rlos ). this rotation has two sources : one originates from the relative movement between the radar and the ship. the other comes from the ship sway ( roll, pitch and yaw )

    機載isar對艦船成像依靠艦船與雷達視線（ rlos ）之間的相對轉動，它由飛機與艦船航行引起的相對運動和海浪作用下艦船自身搖擺（橫搖、縱搖、偏航）產生的轉動組成。
