Currently, creation of space -based P-band radar systems is a vital problem in the development of Earth remote sensing systems. These systems make it possible to solve the problem of monitoring vegetation on the Earths surface, to carry out soil analysis and detect objects detecting hidden in foliage. Such systems are, however, difficult to produce due to the necessity of using large- aperture antenna systems. Expanding active phased arrays and reflector antennas are most common for the task. Structures of this kind are characterized by considerable mass and dimensions, which does not make it possible to regard small satellites as their carriers. A system with an array of four transceiving Yagis is proposed. The systems are shown to possess sufficient characteristics to solve the target tasks. The structures simplicity makes it possible to install the systems on small satellites, which drastically reduces the cost and time of production.
