Research of non-coherent detection in jamming environment

Target detection and tracking in jamming environment is the main problem of airborne radar, while frequency agility is one of the effective measures for radar anti-interference. Received echoes of radar can be divided into the interfered part and the un-interfered part in the state of frequency agility. In this work, target is detected from the un-interfered echoes which are integrated. The setting of detection threshold and the loss of integration are emphatically analysed. Finally, the effectiveness of the proposed method has been validated by experiment data.
