Two-coordinate ship-borne radar signal level fusion method

Abstract

The invention provides a two-coordinate ship-borne radar signal level fusion method. The two-coordinate ship-borne radar signal level fusion method comprises the steps of preprocessing echo data of aplurality of radars of the same type in formation, then uniformly transmitting the preprocessed data to a signal fusion center, converting the preprocessed data into a uniform coordinate system through coordinate transformation, and then realizing non-coherent accumulation of echo data of a plurality of radar targets by utilizing an improved dynamic programming algorithm to realize effective detection of a weak target. According to the two-coordinate ship-borne radar signal level fusion method, the data volume transmitted to the data fusion center by each ship is greatly reduced, and the weaktarget detection performance is improved; the problems of low target parameter measurement precision and difficulty in multi-homotype radar signal level fusion cooperative detection space registrationcaused by huge data volume transmitted between each ship and the data fusion center in the formation and the energy diffusion phenomenon of a dynamic planning method are effectively solved; and a powerful technical support is provided for detection of the weak target in a complex sea clutter environment.

Description

technical field [0001] The invention relates to the technical field of radar cooperative detection, in particular to a radar cooperative detection signal level fusion method. Background technique [0002] my country has a vast ocean area, and the ocean is rich in resources. With the continuous increase of ocean activities, countries began to compete for ocean resources. In recent years, with the continuous deepening of the modernization of my country's navy, naval weapons and equipment have been greatly developed. In the future, my country will have more fleets to safeguard my country's maritime interests. [0003] With the continuous escalation of wars, the combat environment faced by modern shipboard radars is becoming more and more complex. Anti-radiation missiles, integrated electronic jamming, stealth technology and low-altitude / ultra-low-altitude penetration constitute the "four major threats" to modern shipboard radars. . At present, it is difficult to continuously...

Problems solved by technology

[0006] In order to overcome the deficiencies of the prior art, the present invention provides a two-coordinate shipborne radar signal level fusion method, which overcomes the insufficient utilization of the same-type radar detection target information in the naval fleet formation and the transmission between the ship and the data fusion center in the prior art. The huge amount of data and the energy diffusion effect of traditional dynamic programming algorithms lead to the disadvantages of low measurement accuracy of target parameters
