The article proposes an optical layout and presents a detailed parameter calculation of a high-performance objective lens designed for a four-channel incoherent optical correlation direction finder. A feasible solution is developed using currently available materials and manufacturing technologies. However, achieving high optical performance required the inclusion of a significant number of resource-intensive components. Taking this into account, the study further explores the possibility of achieving a compromise improvement in optical characteristics by employing widely used and economically justified optical materials and elements. Two alternative optical configurations for the direction finder objective are proposed and substantiated as part of the compromise design. The first is based on the well-known SOI (State Optical Institute) eyepiece, and the second utilizes a single parabolic mirror. The optical parameters of both configurations are calculated, and their application limitations are discussed. The results obtained enable the development of both a high-performance objective for an incoherent correlation direction finder and a practical compromise variant suitable for experimental correlation signal analysis.
