Abstract: This paper presents a knowledge/rule base system which controls parameters and modes for multi- function/multi-mode sensors such as radar. The system performs a situation assessment of the signaloise environment followed by appropriately prioritized automatic control of the parameters and modes of the sensor system. The work involved software development of an advanced simulated radar interacting with a simulated environment. The most recent activities involved the implementation of the system with a phased array sensor in a real world signaloise environment. The results illustrate the improvement in signal to noise as the system assesses the noisy sensor environment and consequently controls the sensor's parameters and modes. A monitor display also reports the type of noise assessed by the system, i.e. interference, terrain clutter, weather clutter, etc., along with the course of action taken, i.e. sidelobe blanking, frequency agility, Doppler filtering, etc., to suppress such noise.!13
