Problems solved by technology

[0002] Phased array radar scans wave positions according to the wave position table. If the wave positions are too compact, it will inevitably waste radar system resources, and redundant detection of targets will also cause difficulties in decorrelation; If it is too loose, it may cause the loss of target detection

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0023] The present invention utilizes the invariance of the beam width in the sinusoidal space to convert the space domain to the sinusoidal space, and the wave positions are evenly arranged in the sinusoidal space, and the row spacing and column spacing between each wave position are obtained from the beam width, and then the calculated Row spacing and column spacing, so that the wave position evenly covers the entire airspace range, thus forming a wave table of the entire airspace range, such as figure 1 As shown, it specifically includes the following steps,

[0024] Step (1), the user selects any scanning airspace in the corrected spherical coordinate system;

[0025] In step (2), the scan...

Abstract

The invention discloses an airspace staggered wave position arranging method for a phased array radar. The airspace staggered wave position arranging method for the phased array radar includes steps that 1) selecting a scanning airspace under a correction ball coordinate system; 2) converting the scanning airspace under the correction ball coordinate system into a sine airspace under a sine space coordinate system through coordinates; 3) confirming the line space and column space between adjacent wave positions under the sine coordinate system; 4) confirming the wave position arrangement of the whole sine region to generate a wave position table; 5) removing the wave positions outside the airspace range set by a user to form the staggered wave position arrangement of the scanning airspace. The airspace staggered wave position arranging method for the phased array radar uses the sine coordinate system to carry out wave position arrangement on the whole airspace based on covering the required airspace, avoids the change of the wave beam shape along with the wave beam directing, realizes the uniform arrangement of the wave position under the sine coordinate system, guarantees that the 3 dB coverage rate arrives at 90% while the overlapping ratio is 0, and has broad application prospect.

Description

technical field [0001] The invention relates to a method for interleaved wave position arrangement in the airspace of a phased array radar, belonging to the technical field of radar wave position scanning. Background technique [0002] Phased array radar scans wave positions according to the wave position table. If the wave positions are too compact, it will inevitably waste radar system resources, and redundant detection of targets will also cause difficulties in decorrelation; If it is too loose, it may cause the loss of target detection. At present, the traditional phased array radar has two wave position arrangements: the longitudinal wave position arrangement and the overlapping wave position arrangement. Among them, the column arrangement requires the least number of wave positions, but its coverage Low; the overlapping arrangement style, although its coverage rate is high, the overlap rate is also high, which is easy to cause redundant detection of targets. How to re...
