The paper addresses the cooperative interception guidance (CIG) problem for multi-missile systems with line-of-sight angles (LOSA) constraints. A new fixed-time convergence cooperative guidance law (FTCCGL) with LOSA constraints is designed, which consists of two contributions. Firstly, to ensure the simultaneous attack of the multi-missile system under any initial state, an integral sliding mode (ISM) guidance command (GC) in the LOS direction (LD) is developed to achieve the fixed time (FT) convergence of impact time. Secondly, the integral sliding mode guidance commend perpendicular to LD is proposed, which ensures that the LOSA of each missile rapidly get their expected value within FT. Furthermore, based on the FT consensus theory, bi-limit homogeneous technique and Lyapunov theory, the stability of the FTCCGL are analyzed, and the effectiveness and feasibility are verified by numerical simulations.
