Abstract

The invention discloses a method for testing S-shaped interference beams based on a frequency control array, comprising the following steps: S1. Selecting a radar test receiver according to the distribution position of a preset S-shaped interference beam in space of a frequency control array radar transmitter The placement point is the test receiving point; S2, make the frequency control array radar transmitter start to transmit signals, and make each test receiving point receive all the transmitted signal data of at least one preset transmission cycle through the test receiving point; S3 1. Determine the test data of each test receiving point according to the received transmission signal data; S4. According to the spatial position and test data of each test receiving point, draw the two-dimensional beam diagram of the frequency control array, that is, fit the S-shaped interference beam. The invention solves the problems of low practicability, low concealment, low test efficiency, high implementation cost and large capital investment existing in the prior art.

Description

technical field [0001] The invention belongs to the technical field of radar antennas, in particular to an S-shaped interference beam testing method based on a frequency control array. Background technique [0002] As a new type of radar technology, frequency control array radar applies the idea of ​​frequency diversity to array antennas, and obtains beam patterns related to distance, angle and time by increasing the frequency offset of each antenna, that is, frequency control array radar at a fixed time The beam pattern has distance and angle dependence. Traditional phased array beams cannot precisely interfere with irregularly distributed multi-targets. By utilizing the distance-dependent characteristics of the frequency-steered array two-dimensional beam pattern, the synthesized jamming beam with a specific shape can be used to jam multiple targets at the same time. [0003] The existing radar beam test is usually aimed at single antenna components. The conventional test...
