Design of strapdown laser guided seeker

This paper proposes a design of strapdown laser guided seeker with large linear view field, low circuit noise and high precision algorithm. Simulation experiments show that the linear view field is ±12° in the range of ±15° view field, and the spot deviation is better than 1%. Combining traditional calculation method and polynomial fitting method, a fitting algorithm reduces root mean square error 76.9% than Gauss model method.
