Characteristics of detecting the coherent system of selection of moving targets during the matching of the parameters of the square channels.

ntroduction. Operation of adaptive system moving targets selection is considered, which represented by single intermittent subtractor with coherent accumulator, tuned in frequency. System made the form two quadrature channels, high-frequency passive interference and signal from object are converted to video frequency subsequent rejection, accumulation comparison threshold level. Setting task. Investigation effect inevitable practice amplitude phase misalignments channel parameters on detection characteristics targets. Method. Method complex variable used, at input output presented pair real components shifted ninety degrees. Results. Models taking into account possible mismatches channels parameters. The structure processing device shown, includes a series-connected generator object, an cutting filter subtraction circuit frequency-tuned rejection zone, accumulator device. Expressions obtained for correlation functions Dependencies probability correct against background value deviation transmission coefficients mismatch reference voltages different values average spectral density calculated constructed. Conclusion. Significant dependence interference, as well shown.
