In article concidered a problem of space-temporal filtration of random signals in active antennas array with intermodulation distortion in receiver-transmitter moduls. The model of multidimentional Marcovian random process with Gaussian probability distribution density is used for description of random signals. Nonlinear properties of receive channel is specify by model of memoryless nonlinear element. The nonlinearity of this element is approximated by 3 thd order polynome. The synthesis of quasilinear filtration algorithm is implement under condition the power of random signal is considerably greater than power of noise. Analysis of averaged discriminatory characteristic curve demonstrated the matching of its nature with sight and value of nonlinearity coefficient mismatch relatively its optimal value. The perspective of application of achieved results in intermodulation cancellation apparatus are evaluated.
