A high-resolution fuze target detection method

Abstract

The invention provides a high-resolution fuze and target detecting method. The high-resolution fuze and target detecting method comprises the following steps: detecting the distance from a target to a fuze; simultaneously detecting azimuth information of the target and the fuze; and combining the distance and the azimuth information to establish a two-dimensional information database so as to realize fuze and target detection. The method provided by the invention is high in detection accuracy, phase information is acquired by compressing slow time dimension, distance information is acquired by quick time dimension, limitation of recognition of top armor by one-dimensional distance information only is solved, and because target information is added, requirements to target recognition library is reduced naturally; and instantaneity of an algorithm is good, Doppler center fuzzy number can be directly estimated without the aid of a baseband Doppler center, and requirements on tracking instantaneity of a mono-pulse radar guiding head are met. The two-dimensional information combining method is still a blank in the field of fuze at present. The method can be used for a fuze loaded on a missile, and can also be used for a rocket-borne missile system, and the tracking precision of the missile is improved.

Description

technical field [0001] The invention relates to a high-resolution fuze target detection method, which belongs to the technical field of radio sensor target detection. Background technique [0002] The fuze is the core component of the missile ignition, that is, the sensor. By detecting the target and obtaining the target information, it can be judged whether the conditions for detonating the warhead are met, so as to achieve the best coordination for triggering the war. Therefore, whether the fuze can obtain accurate information of the target plays a key role in achieving the best fuze coordination. [0003] At present, in response to the attack of missiles on the roof armor of armored vehicles, most of the industry adopts methods that only rely on improving the distance resolution to obtain roof armor information. The target information is used to judge whether it is a top armor, so as to realize the coordination of leading the battle. The waveforms used are frequency ste...

AI Technical Summary

Problems solved by technology

Because the top armor is flat, it is two-dimensional information. If only one-dimensional information is obtained, the effective detection of the target will be reduced.

At the same time, after the missile enters the target rendezvous area, it is completely uncertain from which direction to launch the electromagnetic wave. Therefore, it is required to establish a complete target recognition library for the one-dimensional distance information of the top armor in order to effectively detect the target. This is quite difficult. of

This method can no longer meet the needs of modern battlefield weapons and equipment in some cases
