Gated range search radar

摘要: Radar apparatus particularly adapted for weather and search operations wherein reflected pulse energy is effectively time gated separately filtered processed output display indication. The transmits relatively low power in directive propagation then mixed with a coherent signal to derive time-displaced doppler frequency electrical signals representative of returned. are as resolution cells lying within predetermined different time-displacement range, from each cell through characteristic filtering networks which provide individual data accordance coordinates or parameters derived antenna scan information travel times the plurality cells.
