A hybrid integration method of frequency agile radar for uniform moving target
Frequency agility (FA) is one of the important techniques in radar systems for the superiority in radar range, glint reduction, electronic counter-countermeasures and so on. However, frequency agility makes the signal processing complex and degrades the detection performance. For uniform moving targets, a hybrid integration method is proposed in group-group frequency agile radar (FAR). The Keystone transform is applied in each group for coherent integration. Due to the FA, a scale transformation based on linear interpolation is proposed, and then the trajectory feature of target is used to achieve the hybrid integration based on Hough transform. The experimental results validate the effectiveness and advantages of the proposed method.
