Outline of Final Research Achievements

A laser radar is an range measurement instrument by means of a laser which amplitude is modulated by an ultra wide-band microwave. It is promising tool to visualize a small structure (centimeters) by remote sensing technique. In this development, we aim to develop a wide-band microwave source, whose output waveform can be controlled digitally. As a result, we successfully develop the digitally controlled microwave source and confirmed that the output waveform can be well controlled in terms of output phase - time accuracy. We also confirmed that output microwave with bandwidth over 4GHz, which can be properly utilized for the laser radar.
