Abstract

Pulse Compression technique is extensively used in radar systems. It improves the Signal-to-Noise Ratio (SNR) of received signal without increasing the peak transmitted power. Non-Coherent Pulse Compression (NCPC) has been recently investigated as a new variant of standard (coherent) pulse compression technique. NCPC uses Manchester-coded pulse compression sequences, such as Barker and Ipatov sequences. This paper proposes a novel technique for implementation of NCPC that is based on well-known m-sequences along with a modified coding scheme. Theoretical evaluation shows that new NCPC technique gives perfect periodic-cross-correlation results (i.e., zero side lobes). Analytical and simulation analysis are performed that show that SNR performance of proposed scheme is comparable to the previously reported Manchester-coded NCPC using Ipatov sequences. It is also demonstrated that compared to previously reported techniques, transmitter and receiver implementation is much simpler in the scheme presented in this article.
