In the Cartesian coordinate system $xOy$, with the origin as the pole and the positive $x$-axis as the polar axis, a polar coordinate system is established. The polar equation of curve $C_{1}$ is $\rho\cos \theta=4$. Let $M$ be a moving point on curve $C_{1}$, and point $P$ is on the line segment $OM$, satisfying $|OM|\cdot|OP|=16$. Find the polar equation of the trajectory $C_{2}$ of point $P$.
