Pulse compression for radar using zero-correlation zone sequence sets
Takao Maeda, Shigeru Kanemoto, Takafumi Hayashi · 2011
The present paper introduces a new approach to the application of sequence set with a zero-correlation zone to the pulse compression of radar. The proposed sequence set has a zero-correlation zone for both periodic and aperiodic correlation functions. The sequences of the proposed scheme can be constructed from a pair of Hadamard matrices of the orders n0and n1. The constructed sequence set consists of n0n1ternary sequences, each of length n0(m+2)(n1+ Δ), for a non-negative integer m and Δ ≥ 2. The zero-correlation zone of the proposed sequences is |τ| ≤ n0m+2, where τ is the phase shift. The inter-subset zero-correlation zone of the proposed sequences is |τ| ≤ Δn0m+2, where τ is the phase shift. The proposed scheme can improve radars using the zero-correlation property of the sequence set.
