Abstract :
The paper considers the processing of constant modulus signals in multi-beam adaptive arrays. The processing is based on the substitution of multi-extreme cost-function of the adaptive filtering process by a linearly constrained quadratic one and the decomposition of the signal processing algorithm for multi-beam array on a number of separate algorithms, related to each sub-array. The simulation demonstrates the signal processing efficiency in the rejection of the interferences.
