| 摘 要： | 针对车载捷联导航系统初始对准中的人为或阵风干扰等问题，提出了一种基于多尺度小波系数内积的干扰信号检测算法。该算法利用惯性敏感器的输出残差来建立用于检测突变信号的跟踪信号，并利用信号边沿或快变部分小波系数表现出的特性，构造了一种小波检测信号，通过小波检测有效地抑制了外界的干扰。粗对准实验证明该算法的有效性。

| Abstract: | In allusion to jamming or flurry happened in strapdown inertial alignment, put forward a new anti-jamming arithmetic based on the multiscale product of wavelet coefficient. After formed a tracking signal from outputs of IMU, and based on special properties of the edge and rapidness in wavelet transform domain, a wavelet detection signal is proposed. The result supports the feasibility of the method. |
