    Abstract

    Radio frequency seeker filter design for homing guidance requirements are highly demanding and challenging. Seeker data is highly noisy and is characterized by correlation, non-Gaussian due to target glint and modulated by radar cross section fluctuations. Over and above there will be periodic data loss due to eclipsing. For generating smooth homing guidance commands an efficient filter having minimum lag and maximum seeker noise attenuation capability is required. This report presents an interacting multiple model seeker filter with extended Kalman filter as mode-matched filter which operates in closed homing guidance loop to generate required guidance commands to intercept maneuvering air-breathing targets. The performance of the seeker filter is evaluated using simulation of different interceptor-target engagement scenarios with different target maneuver profiles.
