Embodiment Construction

[0019] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention.

[0020] The present invention is specifically described as the following process:

[0021] Step 1: The electronic reconnaissance satellite searches for the radiation source target information, and the intercepted signal characteristic information including the target radiation source and the target position information constitute the radiation source target information, and send it to the radar through the satellite downlink;

[0022] Step 2: The radar determines the carrier frequency of the target radiation source signal according to the signal characteristic information of the target radiation source, and the radar adjusts the working frequency band to the working frequency band including the frequency;

[0023] Step 3: The radar adjusts the radar airspace scanning method by changing the scanning cente...

Abstract

The invention provides a method for improving the capacity of a radar for quickly intercepting a key target through satellite detection information. The method comprises the steps that the radar continuously reconnoiters a target radiation source; the target detection information transmitted by a satellite is reconnoitered by connection electrons; a radar frequency domain scanning mode and an airspace scanning mode are adjusted; scanning is executed, and whether the specified target is intercepted or not is judged; if the target is not intercepted, the scanning frequency band is adjusted to execute scanning; and whether the target is the same platform radiation source signal or not is judged according to intelligence information. The method has the beneficial effects that the radar is guided to quickly search and find the target through the satellite wide-area detection capability, meanwhile, the guidance error caused by the curvature of the Earth under the situation of long-range observation is avoided, the problem that the satellite detection information cannot effectively guide the radar under the condition that the radar and the satellite intercept different radiation source signals of the same platform is solved, and thus the capacity of the radar for quickly intercepting a key target radiation signal is effectively improved.

Description

technical field [0001] The invention relates to a method for radar target interception. Background technique [0002] Reconnaissance satellites observe the earth to obtain satellite detection information, that is, radiation source and target information. The information consists of signal characteristic information of the target radiation source and target position information. The satellite detection information can be used to guide the setting of the radar frequency domain scanning method and the radar airspace scanning method. Intelligence information refers to the signal characteristic parameters of different radiation sources of the target platform. By comparing the intercepted signals of different signal characteristic parameters at a specified location with the intelligence information, it can be judged whether the intercepted signals of different signal characteristic parameters at the same location originate from the same platform. [0003] Since platforms usuall...
