摘要：In order to reduce the influence of mutual interference between signals from different transmitters, novel orthogonal signals are designed for netted radar systems in this paper. Different stepped time interval pulse trains (STIPT) which are orthogonal are designed for spatially separated transmitting nodes. Because of the good autocorrelation and cross-correlation properties, mutual interference becomes weaker and signals from different stations can be separated entirely. Furthermore, the proposed approach can reduce distance side lobe and the highest peak to side lobe ratio increases obviously, so the pulse integration can enlarge the detection range greatly. Another advantage is that the proposed approach is compatible to conventional radars and can also be applied to the upgrade of the radars Simulation results show its good performance.
