Moving target detection method, detection device, and mobile detection system

Abstract

The embodiment of the invention provides a moving target detection method, detection device, and a mobile detection system, so that a problem that target echo signals that are detected by the existing mobile detection system during moving target detection include echo signals of fixed targets and thus lots of false alarm targets are generated in the prior art is solved. The method comprises: while a mobile carrier moves, attitude measurement of auxiliary equipment as well as moving speed compensation information obtained and transmitted by a navigation system is received; on the basis of the moving speed compensation information, a corresponding Doppler frequency deviation value of movement, relative to a target, of the mobile carrier is obtained; and according to the Doppler frequency deviation value of movement, relative to the target, of the mobile carrier, a detected target echo signal is compensated, an echo signal of a fixed target in the target echo signal is suppressed, and a Doppler frequency deviation value of the moving target is obtained, thereby obtaining accurate moving target detection distance information and radial speed information.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of radio measurement, and in particular to a moving target detection method, detection equipment and a mobile detection system. Background technique [0002] The existing radio-based detection system uses electromagnetic waves to irradiate the target and receives its echo signal, thereby obtaining information such as the distance from the target to the electromagnetic wave emission point, the distance change rate, azimuth, and height. [0003] However, the existing detection systems, such as radar systems, are mostly set up in fixed positions. Before putting into motion target detection, the antenna needs to be erected, and the radar platform should be leveled through a set of dedicated leveling support system. After the motion target detection is completed, Removal of the antenna and leveling support system is required. In this way, on the one hand, before the shipment is withdrawn, t...

Problems solved by technology

[0007] In view of this, the purpose of the embodiments of the present invention is to provide a moving target detection method, detection equipment and a mobile detection system, which are used to solve the target echo signal detected by the mobile detection system in the prior art when detecting a moving target while traveling. Including the echo signal of a fixed target so that a large number of false alarm targets are generated, at least based on the collected moving vehicle speed information, the detected target echo signal is compensated, and the fixed target in the target echo signal is suppressed.
