Abstract

The invention discloses a phased-array antenna intra-pulse multi-beam implementation method, and the method comprises the following steps that a computer sends a control instruction according to a preset time sequence, and the sending is completed during a pulse cut-off period; after the T/R module receives the control instruction, control data of the control instruction is found out by using a table look-up method during a pulse cut-off period, all the control data are assigned to ten data latches of each channel of the beam control circuit in advance, and after assignment is completed, the assignment circuit is in a high-resistance state; pulse signals are added to the control ends of the ten data latches, and when a pulse arrives, data in the ten data latches are sequentially output under the control of the pulse, and the phase of the microwave phase shifter is controlled. Therefore, according to the method for realizing the multiple beams in the pulse of the phased-array antenna, the data transmission quantity of beam control is reduced, the data is written in by looking up the table, the speed is improved, and the control of the multiple beams in the pulse is realized.

Description

technical field [0001] The invention relates to the field of microwave technology, in particular to a method for realizing intrapulse multi-beams of a phased array antenna. Background technique [0002] In surface-to-air missile weapon systems, time is a precious resource. The intrapulse multi-beam antenna can complete the search of large airspace in a short time. It can be used as the search radar and target indication radar in the surface-to-air missile weapon system, and quickly provide the position and speed information of the target for the guidance radar and missile. For example, the search radar of the Russian Doyle weapon system uses an intrapulse three-beam antenna, that is, three pulses are included in one pulse, and the interval between each pulse is 100nS. Each time the antenna scans, it can be scanned by three beams in the elevation direction. 32 degrees, which not only improves the data rate of the guidance radar, but also improves the angular resolution in th...
