A simulation test device for missile-borne synthetic aperture radar

Abstract

The invention provides a missile-borne synthetic aperture radar simulation test device comprising missile-borne platform attitude simulation equipment, missile flight parameter observation equipment, data transformation and navigation data generation equipment and data acquisition and analysis equipment. With application of the missile-borne synthetic aperture radar simulation test device, the tested missile-borne synthetic aperture radar works on the ground, simulation testing is performed on the tested missile-borne synthetic aperture radar, and the test result and the test result of mounting the synthetic aperture radar on the missile have the comparability close to reality so that one-time consumption cost and test risk of missile-borne SAR mounting can be avoided by the device.

Description

technical field [0001] The present invention generally relates to the technical field of synthetic aperture radar testing, in particular to a missile-borne synthetic aperture radar simulation testing device. Background technique [0002] Synthetic Aperture Radar (SAR) is a high-resolution imaging radar. As an active microwave remote sensing device, SAR relies on its own microwave radiation to work, and is not affected by weather and sunshine conditions, and can image all-weather and all-weather; SAR Using the side-view imaging method, the mapping zone can be far away from the flight track, which is conducive to the flight safety of the carrier; SAR can obtain high resolution and high imaging accuracy, and its theoretical azimuth resolution is compatible with the radar operating wavelength, aircraft flight altitude, radar The distance-independent function works effectively in space or in the atmosphere, which further expands its application range.

Problems solved by technology

[0008] However, for the missile-borne SAR system, its target platform (missile) is disposable, so it is difficult to carry out SAR system testing and SAR parameter adjustment during the development process, as well as SAR during the production process or maintenance process on the target platform For system testing and performance verification, other aircraft platforms are used for flight testing, and its flight characteristics are far from those of missiles, which affects the effectiveness of SAR system testing
