  This study explores the effect of quenched disorder on the characteristic of
self-propelled particles in one-dimension. Here,particles interact with
disorder which serve as directional cues. The study investigates how the
density of the disorder influence the emergence of ordering and clustering in
the collection of the self propelled particles. We introduce the microscopic
model as well as corresponding coarse-grained equations of motion for the local
density and the orientation of particle. Disorder affects the macroscopic
ordering in the system, the size of the ordered clusters decays algebraically
with disorder. Further, the disorder also affects the clustering of particles;
in the presence of disorder, a big macroscopic cluster breaks into small
clusters, leads to the localization of particles around it and results in high
density around the disorder.
