In an infrared monitoring and tracking device that rotates around a vertical axis and monitors the surrounding situation, it consists of an imaging system consisting of an amplification circuit that amplifies the image signal output from the imaging system, and a rate table that rotates the imaging system. An infrared monitoring and tracking device characterized in that the drive frequency of a detector is controlled in response to changes in . (2) The infrared monitoring and tracking device according to claim (1) of the utility model registration, characterized in that the drive frequency of the detector is controlled to be a linear function of the cosine of the elevation angle in response to changes in the elevation angle. . (3) A reference clock signal generation circuit that inputs a clock signal having a frequency proportional to the angular velocity of the rate table and outputs a reference clock signal having a frequency that is an integral multiple of the clock signal, and a circuit that controls the multiple value. Utility model registration claim (2) characterized in that by controlling the numerical value so that it becomes a linear function of the cosine of the elevation angle, the driving frequency of the detector is made to become a linear function of the elevation angle as a result.
