A New Class of Pulse Compression Codes and Techniques.

Abstract

A new class of symmetrical polyphase codes is introduced that promises to be very useful in pulse expander-compressor circuits for radar systems. These codes are very compatible with digital signal processing techniques. The code symmetry permits digital pulse expander-compressors to be implemented with less hardware than required with any previously known code. Another significant advantage of the new codes is that precompression bandwidth limiting such as normally would be found in any well-designed radar actually improves the mainlobe to sidelobe ratios obtainable with the new codes while it degrades that obtainable with the previously known Frank code.
