N2 - Due to the complex and harsh launching and flying environment of guided projectile, gyros strapdown to projectile is easy to fail, and projectile angular rate cannot be accurately sensed. In this article, an online estimation model of projectile angular rate is established, which describes the mathematical relationship among output information of magnetoresistive sensors, the angular rate of gyro output, and attitude matrix. In order to realize the real-time estimation of projectile angular rate, an improved sparrow search algorithm (ISSA) is proposed. This method combines adaptive dynamic step strategy with dynamic compression search strategy, improving the traditional SSA. This method takes angular rate as the optimization object and uses the ISSA diagonal rate estimation model to solve and obtain high-precision estimation of angular rate. The simulation results verify the correctness and feasibility of the online estimation model of projectile angular rate only using magnetoresistive sensors, and the precision of angular rate estimation based on the ISSA is better than that of the traditional intelligent optimization algorithm.
