“…First, some researchers have been putting their effort to investigate effects of the scale factor errors on a terminal homing guidance loop [1][2][3][4]. With this approach, the stability regions of the parasite loop, involving the strapdown homing seeker, were analyzed in several studies [5][6][7][8]. As the second research direction, some efforts have also been made to devise new homing guidance laws, corresponding terminal homing guidance loops [9][10][11], and guidance filters for the strapdown seeker [12][13][14].…”

“…This kind of structure not only reduces the size and mass of the seeker but also improves the aerodynamic performance of the missile body. The roll-pitch infrared seeker has the characteristics of infrared imaging guidance, strapdown guidance, large field of view, and miniaturization so that it is very suitable for short-range combat air-to-air missiles [14][15][16].…”

We propose a new DRR (Disturbance Rejection Rate) compensation method of a roll-pitch seeker based on ESO (extended state observer). The characteristics of a roll-pitch seeker and the DRR definition of two frames of a roll-pitch seeker are analyzed. The influence of different interference torques and different frequency bandwidths on the compensation effect is analyzed. Modeling and simulation of the guidance system of a roll-pitch seeker with the parasitic loop of DRR are carried out. Influence of the new DRR compensation method on dimensionless miss distance is analyzed. Mathematical simulation is established to compare the new ESO-based DRR compensation method with the existing methods such as the feedforward method and Kalman filter method. The analysis and simulation results show that the new ESO-based DRR compensation method has the advantages of high precision, good applicability, and easy adjustment, and the new method can effectively reduce the dimensionless miss distance with different types of input errors. The research of this proposed new method can provide a reference for the latest generation air-to-air missile operations in a high-altitude and high-speed environment and the high-precision research of a roll-pitch seeker.

“…Willman stated that unconformity between the beam control unit of the phased array radar seeker and the rate gyroscope would produce the DRE problem [7]. Bai et al provide in-depth analysis of the work of the parasitic loop in the guidance loop induced by the DRE problem on the gimbal phased array seeker and the influence of missile body disturbance on the seeker performance [8]. Lu et al analyzed the effect of the phased array seeker with PBT for the missile detection and guidance system [2].…”

The radome error and beam pointing error found commonly in the strapdown phased array radar seeker can cause coupling between the missile body motion and the seeker model, impacting the output precision of the seeker and causing the disturbance rejection effect (DRE). Aiming to address the serious impact of DRE on the missile guidance and control system, a strapdown phased array radar seeker DRE parasitic loop (considering radome error and beam pointing error) is established. The DRE parasitic loop is analyzed. The main aim of this paper was to develop a novel online estimation and compensation method for a DRE parasitic loop using an extended state Kalman filter, which was compared with an extended Kalman filter and a strong tracking unscented Kalman filter. The simulation results show that the proposed online estimation and compensation method for the DRE parasitic loop can estimate the radome error slope and beam pointing error slope stably and accurately from the initial velocity pointing error input and the large initial estimation error. Effective suppression of the DRE problem and compensation for the line-of-sight angular rate output in real time is achieved. Furthermore, the guidance system performance and precision are both improved.INDEX TERMS Active disturbance rejection control, beam pointing error, disturbance rejection effect parasitic loop, extended state Kalman filter, radome error.
