Stochastic Whitewash of Passive Correlated Interference for the Optimization of Moving Target Selection Systems
Abstract
Purpose: When processing radar signals for suppressing passive correlated interference, the notch filter order can vary from the maximum value down to zero (filter off), resulting in the need for real-time alignment of the output noise level and the added phase and group delays. Another need is the minimization of the loss of a useful signal caused by mismatched filtering. The aim of the work is determining the conditions for target visibility in the system built on the basis of the canonical structure with random parameters. Results: The "stochastic whitewash" principle was grounded and formulated. A canonical structure was proposed for a stochastic filter with a permanent order, namely: a stochastic compensator for the interference zone and an energy-transparent stochastic filter for the noise zone. According to the efficiency characteristics (threshold characteristics of weak signal detection), the deterministic and stochastic systems were proven to be equivalent. Practical relevance: The obtained result will help to achieve a constant level of the output noise and false alarms, reducing the demands for the digit capacity of the signal processing system. With the space-frequency interpretation of the controlled coverage parameters modulation process, it will also help to reduce the aircraft visibility.Published
