摘要 | In order to analyze line-of-sight(LOS) angular rate accuracy factors of the strapdown imaging seeker, LOS angular rate accuracy calculations algorithm is proposed. LOS angular rate estimation algorithm is derived, and "differential + Steady state Kalman" algorithm is used to estimate body LOS angular rate. The error sensitivity of each error source is analyzed in detail using the error theory, and LOS angular rate accuracy calculation algorithm is presented. The error characteristic and causes of body LOS angle, body angular rate, attitude and body LOS angular rate are investigated. The verification system of the LOS angular rate accuracy calculation algorithm is established and experiment is carried out. Results show that estimation accuracies of the LOS elevation angular rate and the azimuth angular rate are 0.273/s and 0.235/s, experimental results are 0.281/s and 0.242/s, and relative errors are 2.85% and 2.89%, respectively. Experimental results also verify the correctness and accuracy of the algorithm. The results can be used to the whole strapdown imaging guidance and control system design process, and it provides a theoretical basis for the accuracy of the LOS angular rate estimation and indicator allocation. , 2015, Science Press.
