Embodiment Construction

[0069] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0070] The air-fed simulation method has been fully verified in the 2-18GHz seeker simulation test. Compared with the high-frequency band, the three-axis turntable for simulating the attitude of the projectile in the darkroom has a significant impact on the seeker in the low-frequency band. Therefore, this method has not been applied to low-frequency (200M ~ 2GHz) seeker simulation experiments before.

[0071] Aiming at the potential influence of the turntable on the seeker, the present invention proposes an air-feed low-f...

Abstract

The invention discloses a space-fed type low-frequency homing hardware-in-the-loop simulation test method. The method includes: constructing a space-fed type low-frequency homing hardware-in-the-loop simulation system; determining an antenna array position control instruction based on a transformation relation among an inertial coordinate system, a body coordinate system, and a laboratory coordinate system in a darkroom; determining a control angle of a rotary table; controlling an antenna array and the tri-axial rotary table; and acquiring attitude motion information and target information. The invention also discloses a space-fed type low-frequency homing hardware-in-the-loop simulation test system. According to the method and the system, the influence of the rotary table on the detection precision of a seeker can be thoroughly eliminated by employing the modes of externally arranging the rotary table and fixing the seeker, the technical problem of space-fed low frequency is solved, and space-fed type low-frequency homing hardware-in-the-loop simulation tests are accurately and vividly accomplished.

Description

technical field [0001] The invention relates to the technical field of semi-physical simulation tests. More specifically, it relates to a semi-physical simulation test method and system for air-fed low-frequency homing. Background technique [0002] Hardware-in-the-loop simulation is a technology that connects the controller with the simulation model of the control object realized on the computer for experimentation. In this test, the dynamic characteristics, static characteristics and nonlinear factors of the controller can be truly reflected, so it is a simulation test technology that is closer to reality. This simulation technology can be used to modify the controller design (that is, before the controller is installed in the real system, the design performance of the controller is verified by half-physical simulation. If the system performance index does not meet the design requirements, the controller can be adjusted. parameter, or modify the design of the controller)...
