Synthesis of non-regular multitone signals and algorithms of their processing

A new approach of irregular multifrequency signal processing for short wave (SW) and ultra SW radar is discussed. These signals have advanced noise stability to noise background due to the flexible energy distribution in the spectral range. They have improved electromagnetic compatibility in comparison with other electronic systems. A number of parametric algorithms were synthesized for irregular multifrequency signal processing. They are based on the autoregressive model. The results of the signal-algorithm approbation are discussed. This approbation was completed with the help of an experimental SW radar used for sea surface monitoring.
