In this article, we mainly study the polycyclic codes over $S$, where $S = \mathbb{F}_q+u\mathbb{F}_q$ with $u^2 = u$. First, the annihilator self-dual codes, annihilator self-orthogonal codes and annihilator ${{{\rm{LCD}}}}$ codes over $S$ are also introduced and studied. Next, we define a Gray map from $S^n$ to $\mathbb{F}^{2n}_q$ and investigate the structure properties of polycyclic codes over $S$ using the decomposition method. The Hamming distances of the Gray images are also determined by their decompositions. Finally, we obtain some good codes based on the results.
