Photoelectric detector is widely used in the military; it is mainly used to measure the azimuth of the air target. This paper mainly studies the requirements of the aircraft maneuvering when the photoelectric detector is pure angle measurement of air maneuvering targets. According to the principle of the pure angle detection of the photoelectric detector, using the maximum likelihood estimation method, the calculation formula is deduced, and a calculation method is presented. Keywords—Maximum likelihood estimation method; Pure angle measurement; Solving formula; Photoelectric detecting device

Study on the Application of the Pure Angle Measurement of the Photoelectric Detector in the Aerial Maneuvering Target-Take the photoelectric radar as an example
