The invention relates to a long-baseline small-deformation array antenna housing truss for a three-dimensional imaging radar. The truss comprises a truss assembly, a pull rod assembly, an antenna housing assembly, an antenna assembly and an electromagnetic wave absorption assembly. Wherein the truss assembly is in a flat plate shape and comprises a truss, bulkheads, cross beams and hoops, fairing supports composed of the bulkheads and the cross beams are arranged on the front edge, the rear edge, the left side and the right side of the truss, and the hoops are arranged on a radar mounting surface and used for fixing and binding cables or pipelines; the pull rod assembly comprises a pull rod and a connector. The truss assembly and the fuselage are connected to the belly and a side wall stringer through the pull rod assembly. The radome assembly comprises a plurality of radomes, and the radomes are uniformly distributed on the bottom surface of the truss assembly and are connected with the truss assembly through stainless steel bolts; the antenna assemblies comprise three-dimensional imaging radar array antennas and installation structural members, the number of the antenna assemblies is the same as that of the radomes, and the antenna assemblies are independently installed in the radomes respectively.
