TLDR
The output response of a matched filter for several cases of combined Barker codes is computed for various amounts of Doppler mismatch, and it is shown that combined Barker code, like conventional Barker codes, are extremely sensitive to Dopplers shift.Abstract:

Self-Clutter Cancellation and Ambiguity Properties of Subcomplementary Sequences
TL;DR: In this paper, a class of waveforms described in an earlier paper as the subcomplementary set of sequences which are basically repetitive and Hadamard coded, exhibit the property of cancelling self-clutter completely in the delay-Doppler plane if their ambiguity functions are combined.

On generation and measurement of combined Barker codes
TL;DR: A code generator for the combined Barker code 13 × 4 is described in this paper and measurements of the autocorrelation function and the power spectrum of this code are presented and are compared with derived exact expressions.

Improved ASM-TER Training Sequence Detection and Fine Doppler Frequency Estimation Methods from a Satellite
TL;DR: To detect terrestrial application-specific messages (ASM-TER) signals from a satellite, a novel detection method based on the fast computation of the cross ambiguity function is proposed in this paper, and the computational complexity is greatly reduced.

Uncorrelated binary sequences of lengths 2a3b4c5d7e11f13g based on nested Barker codes and complementary sequences.
TL;DR: In this article, an algorithm to generate binary sequences completely uncorrelated with certain sets of complementary sequences is presented, and it is compared with a previous proposal based on an iterative algorithm.
