This paper proposes a radar fuse system using random pulse position modulation signals in combination with random binary phase coded modulation. Mathematical model of the fuse signal is defined and its average ambiguity function is presented. The fuse system principle is then given and its anti interference performance analyzed. The results show that the proposed system has good range and velocity measurement performances, very low probability of interception, and is excellent in anti interference.
