An opportunity research of small size AESA use in microwave range wavelength for target detection

Radar systems based on phased antenna arrays (FAS) are used to detect and track objects in the microwave wavelength range. It is proposed to use small-size phased antenna arrays for detection and tracking of objects. The most suitable in this case are the centimeter and millimeter ranges (frequencies: 23 ... 24 GHz, 33.4 ... 36.00 GHz and 73 ... 74 GHz), which allow to achieve the best directivity characteristics of the antenna system. To estimate the limiting values of the antenna system, its characteristics for the frequency f = 100 GHz are calculated. The prototype is made of square antenna elements.
