Short summary
In this paper, we study the compensation method of the helicopter towed bird. We will affect the compensation results based on the geomagnetic gradient. Therefore, we build a compensation model based on the geomagnetic gradient, which is 6 % higher than the traditional model. When the helicopter towed bird system is used for magnetic target exploration, this method can be used to eliminate the interference generated by the helicopter towed bird system and further accurately detect the target.
