%X <p>In order to improve the joint distance-velocity-resolution of the composed linear frequency modulation (CLFM) signal, a rotated linear frequency modulation (RLFM) signal based on fractional Fourier transform is proposed. The design method of RLFM signal is given, and the simulations of the signal about the ambiguity function, -3dB ambiguity graph, distance ambiguity graph and velocity ambiguity graph have been presented. Finally to put RLFM signal and CLFM signal are compared. The differences of them show that the RLFM signal has a better performance on velocity resolution and joint distance-velocity- resolution than the CLFM signal.</p>
