Title:
MULTI-CONSTRAINT MILLIMETER-WAVE VEHICLE-MOUNTED MIMO RADAR ANTENNA ARRAY DESIGN METHOD, AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/279737
Kind Code:
A1
Abstract:
Disclosed in the present invention are a multi-constraint millimeter-wave vehicle-mounted MIMO radar antenna array design method, and an apparatus. The method comprises the following steps: determining the number of transmitting array elements and the number of receiving array elements of an MIMO radar antenna array; constraining an array aperture according to the resolution requirement of an MIMO radar and the size of a PCB; constraining a minimum array element spacing according to a physical size of an antenna unit; constraining the distribution range of each antenna array element according to the number of chips, a transmitting array aperture and a receiving array aperture; optimizing an MIMO radar antenna array design by using a genetic algorithm, and generating an initial population, wherein each individual in the population represents an array arrangement mode; calculating the fitness of each individual by means of a fitness function, and performing selection, crossover and mutation operations on individuals in the population, so as to generate a new population; and determining whether a termination condition is met, and if so, outputting optimal individuals, i.e. optimized array arrangement modes. According to the present invention, by means of a plurality of constraint conditions, an optimized MIMO radar antenna array better meets actual application requirements.
