Abstract: We consider operators of the form: $\int _{ - \infty }^\infty {{F_t}\varphi (t)\;dt}$, where ${F_t}$ is a $1$-parameter family of Fourier integral operators and $\varphi (t)\;dt$ a tempered distribution on the real line and show that these operators are sums of pseudo-differential and Fourier integral operators. Here, we give the typical case where $\varphi (t)\;dt = {\text {p}}.{\text {v}}.\left \{ {1/t} \right \}$. An application to singular integrals on variable curves is given.
