The Intelligent Reflecting Surface (IRS) is a promising technology for overcoming the coverage hole problem in millimeter wave communications; This equipment consists of many tunable passive elements and can reflect the incident wave in the intended direction. Physical optics (PO) approximation is used to calculate the path loss of the transmitter-IRS-receiver link. However, a higher computational cost is required as the number of passive elements increases. To address this issue, we propose a path loss estimation method based on the radar equation. Specifically, we have improved the radar equation using the first Fresnel zone within the IRS. Our proposed method can calculate the path loss more simply than PO approximation, less amount of calculation. In this paper, we show the effectiveness of the proposed method for arbitrary reflection positions with measurements and numerical simulations.
