Ku-band sea clutter measuring radar

Abstract

The invention relates to a Ku-band sea clutter measuring radar which is mainly composed of an antenna feed system, a transmitting system, a receiving system, a signal processing system, an environment monitoring system, a photoelectric tracking system, a servo system, a power supply system and a control system, wherein the antenna feed system is connected with the transmitting system and the receiving system respectively, the transmitting system and the receiving system are connected with the signal processing system, the signal processing system is connected with the control system, and the control system is respectively connected with the servo system, the environment monitoring system and the photoelectric tracking system. The Ku-band sea clutter measuring radar has the following advantages that: the radar has the measurement capability under the conditions of multiple directions, multiple frequency points and small grazing angle; and equipment can be remotely controlled through software. The Ku-band sea clutter measuring radar aims at completing measurement of sea clutter time and polarization properties and data storage by simulating the tail end movement environment of a high-precision guided weapon. A sea clutter database under various sea conditions is established and is used for simulating various battlefield environments afterwards and evaluating the clutter interference resistance of the high-precision guided weapon seeker.

Description

technical field [0001] The invention relates to the technical field of electromagnetic technology, in particular to a Ku-band sea clutter measurement radar. Background technique [0002] When the radar detects sea targets in sea-facing mode, it will inevitably be affected by complex sea surface echoes, namely sea clutter. How to effectively suppress sea clutter and maximize the accumulation of target echo energy, thereby weakening the adverse effects of sea clutter and improving the detection performance of sea targets is a very exploratory and difficult bottleneck theoretical and technical problem, and it is still a problem in the field of radar applications. Important and difficult issues to be further resolved [0003] The basic prerequisite for weakening the adverse effects of sea clutter is to carry out research on the characteristics of sea clutter, fully grasp the law of sea clutter characteristics, and make reasonable and effective use of sea clutter characteristics...
