Abstract

The track before detect technology based on Hough transform is an effective method for hypersonic target detection, but this method requires the target to move as linearly as possible. In practice, hypersonic targets often generate significant maneuvers during flight, such as “snake maneuver” where the accumulated values from the previous time will have a notable impact on the accumulated values at the current time. Aiming at this issue, this paper proposes a recursive accumulation method based on attenuation factor. By setting an attenuation factor with a value less than 1 and using time difference as the power of the attenuation factor, the accumulated value at the previous time is weakened, ensuring that the accumulated value at the previous time can be accumulated while reducing its impact on the current accumulation. At the same time, it avoids the computational burden caused by the continuous deletion and addition of measurement point information in the original recursive method, which has certain application prospects.
