Abstract :
Pulse compression is commonly used in radar applications to improve range resolution while keeping transmitted peak power low. Conventional approach is either using SAW devices or fast convolution processing, but either solution has significant drawbacks. In this work, analog pulse compressor based on analog matched filter has been proposed using a digital waveform generator and an analog correlator. This scheme not only has advantages over conventional methods, but also adds additional flexibility to the system, and opens up possibilities for future extensions.
