Abstract
We demonstrate the use of stimulated echoes for high-speed phase-modulated signal processing. The specific example chosen here involves the compression of biphase-coded pulses-a technique widely used in radar systems to achieve high range resolution and high signal-to-noise ratios. Experimental results obtained with the 5- and 13-bit Barker codes are presented, along with the measurements of a system's dynamic range and signal-to-noise enhancement. Advantages of this technique over the existing methods for signal processing are discussed.Keywords
