The invention provides a semi-physical radio frequency simulation triple feed coefficient determination method for a chaff cloud, and belongs to the technical field of semi-physical radio frequency simulation and chaff cloud passive interference. The method comprises the following steps: carrying out azimuth division on an area where chaff clouds are located according to the fact that the chaff clouds are projected into different triples to obtain a plurality of sub-areas with different orientations; determining the number of chaff in each sub-area; calculating the feed coefficient of the semi-physical radio frequency simulation triad of the single chaff of which the position and orientation are randomly distributed in the sub-area; determining a joint probability density distribution function of a semi-physical radio frequency simulation triple feed coefficient of the chaff clouds in the sub-areas; and based on the determined joint probability density distribution function, giving a sample of the feed coefficient of the semi-physical radio frequency simulation triple of the chaff clouds of each sub-area, and superposing the feed coefficients of the same radiation unit of each sub-area to obtain the actual feed coefficient of the radiation unit. According to the invention, the calculation time of the feed coefficient can be greatly reduced.
Description
technical field [0001] The invention relates to the technical field of hardware-in-the-loop radio frequency simulation and chaff cloud passive interference, in particular to a method for determining triplet feed coefficients for half-in-the-loop radio frequency simulation of chaff clouds. Background technique [0002] In the complex electronic environment of the modern battlefield, chaff jamming, as an effective form of passive jamming, plays an important role. With its outstanding features such as simple manufacture, low price, and large interference range, it is widely used in scenarios such as aircraft missile penetration and ship self-defense. In order to evaluate the effect of chaff interference, relevant experiments can be carried out in the field test environment, which requires a lot of money. In order to effectively evaluate the performance of chaff jamming and to carry out experiments more economically, the echo signal of chaff jamming can be modeled and simulated...
