Abstract
A surface acoustic wave (SAW) device in a pseudo-coherent moving target indicator uses a common input transducer to delay both reference and signal inputs to a mixer by varying amounts. The mixer produces a Doppler signal which is processed within a single range cell. The SAW device may contain additional delay paths which drive other range cells. Power splitting and amplification sections of the moving target indicator are minimized through use of the SAW device.
