Purpose

The purpose of this study is to investigate the design parameters of an optimal SAR satellite sensor on remote sensing missions. Synthetic aperture radar (SAR) satellite missions, with the advantages of using all weather conditions, repetition of a pass, high spatial resolution and adequate balance, can not only provide timely coverage in disaster areas but also environmental monitoring and accident assessment. It also provides resources. The product of images depicts the needs of government organizations not only before and after the crisis but also during the crisis. Therefore, low-cost SAR satellite loading efforts have begun with SAR satellites and key technologies.

Design/methodology/approach

Information about the basic parameters of SAR satellites such as antenna dimensions, image resolution, pulse and relationship repetition, as well as the tradeoff between required parameters and design needs’ evaluation was achieved. In this paper, the tradeoff methods between some technical requirements are presented, and the limitations in the design of a SAR prototype sensor in the X band are examined. Diagrams can provide a complete overview of the predicted fluctuations and tradeoffs between them for a designer.

Findings

Analysis of findings reveals that data transmission rate with PRFmin is independent of antenna incidence angle, but in contrast, it is dependent on PRFmax, and afterward its relationship was analyzed. Drawn diagrams approved presented design and calculations. Other important parameters in the design of the SAR sensor such as antenna dimensions, tilt angle, amplitude and resolution of azimuth can be achieved as significant elements in systematic design according to the results of this paper. Regarding the displayed diagrams, it can be understood that the angle of the antenna should not be from 15 to 60 degrees.

Originality/value

This paper provides an overview of the new observational capability offered by the second generation of SAR sensors, especially in the field of remote sensing applications. The built-in antenna is built for the small SAR sensor. This array antenna is designed with a parallel screen to work in X-frequency with vertical polarity.
