Research on Calculation Method of Missile Miss Distance Based on Single Station Radar Measurement Data

Miss Distance is an important parameter to characterize the missile strike performance. Using single-station radar measurement is a commonly used method for measuring the miss distance in the range. The error of miss distance calculated by directly using the original radar measurement data is large. This paper considers that the missile and target have a high speed and a short time at the intersection stage, and the two can be equivalent to a uniform linear motion. Under this premise, this paper proposes a method of least square linear fitting the original radar measurement data and calculating the miss distance based on the fitting data. The simulation results show that, when the method in this paper is used to solve the miss distance, the error of the miss distance calculated based on the measurement data of the typical phased array radar in the range can be controlled at the meter level, which basically satisfies the measurement accuracy requirements of the miss distance in the missile shooting test.
