Problems solved by technology

For ultra-high-speed moving targets, the target has already traveled a relatively large distance within the time of building the flight, which is not conducive to the rapid interception of the target

Embodiment Construction

[0015] The present invention adopts the method based on the TAS precise tracking beam to be applied to the rapid navigation of low-altitude and high-speed targets. The following is a rapid navigation of a target with a distance of 30Km, an azimuth of 90 degrees, a speed of 800 m / s, and a direction that flies radially to the radar. The implementation is described in detail, as attached figure 1 shown:

[0016] 1. The operator selects the quick start button on the display console to be effective. After finding the echo of the target on the video echo screen of the radar, click on the screen with the mouse to record the azimuth and distance of the target. Admission error, if the admission value is 31Km distance, azimuth is 89 degrees, and the quick start command containing the azimuth and distance information of the admission target is sent to the data processing;

[0017] 2. After the data processing receives the command, use the nearest neighbor rule in the radar echo point tr...

Abstract

The invention relates to a fast navigation method for a low-altitude high-speed target based on a TAS precise tracking beam, which is mainly suitable for the fast navigation of a moving target by a rotating phased array radar, and is especially suitable for the rapid navigation of a low-altitude sea-skimming high-speed target. In the traditional navigation method, the sampling period of the radar to the target is the same as the rotation period of the radar. When searching for navigation, it generally takes 6 to 7 rotation periods, which takes a long time and is difficult to meet the rapid navigation requirements for ultra-high-speed targets. The invention makes full use of the two-dimensional phase sweep characteristics of the phased array radar, and through rapid response to emergency tasks, the target is sampled multiple times in one antenna cycle, and the target is quickly established within one cycle.

Description

technical field [0001] The invention belongs to the field of shipborne rotating phased array radar. Background technique [0002] The fast and stable tracking of the incoming target by the shipborne warning radar (the track quality reaches 7) is of great significance for the timely and accurate interception of the weapon system. The traditional method of establishing navigation for the target is: when the radar antenna sweeps the target , the received echoes are detected and judged over the threshold, and when a target point over the threshold is found, it is recorded and saved. When the radar antenna rotates to sweep the target azimuth for the second time, within a certain airspace range near the target point that passed the threshold last time, the received echoes are detected and judged over the threshold again. If there is a point that has passed the threshold, then the points that appear twice are correlated to form the initial track. And according to the position inf...
