Abstract

The invention discloses a microwave staring correlated imaging random radiation array element spatial arrangement optimization method. The method includes acquiring the random radiation array area and the minimum distances, diameters and numbers of the array elements; performing optimization by adopting the rule of array element arrangement entropy maximization by the genetic algorithm, and acquiring the maximum arrangement manner of the array element arrangement entropy. By the aid of the method, the randomness of the radiation field can be improved, and the high-resolution imaging is implemented.

Description

technical field

[0001] The invention relates to the technical field of radiation source design, in particular to an optimization method for spatial arrangement of random radiation array elements in microwave staring correlation imaging. Background technique

[0002] Microwave staring-associated imaging refers to the use of radar located on a stationary platform to image a fixed area, which can achieve continuous staring observation and imaging of a specific area. Traditional staring imaging, that is, real-aperture imaging, its angular resolution is limited by the aperture of the actual antenna array, which limits its practical application.

[0003] The high-resolution microwave staring correlation imaging system based on the space-time two-dimensional random radiation field interacts with the target in the fixed staring area by constructing the space-time two-dimensional randomly changing radiation field, and performs information processing through the received scattered ech...
