Abstract

The invention discloses a comprehensive testing platform for a high-resolution jogging target imaging system. The platform comprises a microwave darkroom; a target model; a target movement platform which is located on a platform substrate of the microwave darkroom, and is used for bearing the target model and driving the target model to move and to rotate on the target movement model; an antenna system which is used for receiving and transmitting electromagnetic waves, is located on a side surface of a moving track of the target movement platform, and moves towards the target model; a microwave assembly which is used for carrying out the echo amplitude and phase measurement of the target model and collecting the imaging data; and a controller which is used for controlling the target movement platform and the antenna system. The platform provided by the invention can truly simulate the spatial movement posture of a load, and the high-resolution imaging system carries out the measurement of the target, and completes the strip-type two-dimensional imaging measurement of a jogging target. The platform can achieve the effective verification and / or testing of and ISAR mechanism.

Description

technical field [0001] The invention relates to the technical field of microwave imaging radar, in particular to a high-resolution micro-moving target imaging system comprehensive test platform. Background technique [0002] Inverse synthetic aperture radar (ISAR) is a kind of microwave imaging radar. It uses pulse compression, relative motion between target and radar to obtain high-resolution images of targets, especially non-cooperative military targets, and has high coherent signal processing gain. [0003] With the development and maturity of broadband radar imaging and recognition technology, ISAR has shown great application potential in military fields such as aerospace target monitoring, aviation target imaging, missile guidance and ballistic missile defense, throughout the target recognition, true and false target recognition , homing guidance and precision strikes and other important military applications. Similarly, ISAR also has broad application prospects in civ...
