Abstract
The invention discloses a radar interference integrated waveform design method based on an iterative fractional programming algorithm, and belongs to the field of radar signal processing. Aiming at a waveform design problem of a radar interference integration (IRAJ) system, the invention considers maximization of a signal to interference plus noise ratio (SINR) of the IRAJ system under constraints of energy and peak-to-average ratio (PAR), and in order to solve a generated non-convex multi-objective optimization problem, an iterative fractional programming algorithm based on an alternating direction multiplier method (ADMM) is provided, and an optimal waveform is obtained by a loop iteration optimization method. The method has good performance in the aspect of target detection while suppressing interference is carried out on the threat radar, and the total calculation complexity of the proposed algorithm is in linear relation with the number of iterations and is not greater than the quadratic relation with the code length.
