An innovative aperiodic phased array antenna architecture with quantised excitation for space‐borne synthetic aperture radar (SAR) is presented. Compared to traditional periodic arrays, the proposed array antenna enjoys two major advantages including (i) much higher overall power efficiency and (ii) phase‐only control for both transmitting (TX) and receiving (RX) patterns to fit different space SAR beam shaping and steering requirements. The unprecedented studies on the quasi‐optimum TX and RX pattern strategies for space SAR are carried out and this strategy is utilised in the design of the proposed aperiodic phased array. Performance of the proposed array when being applied to space SAR are evaluated. Moreover, the authors obtained positive results which endorse the design.

The paper presents the design guidelines for Active SAR Antennas followed for the development of COSMO Sky Med SAR Antenna Subsystem. They have brought to define the antenna architecture, the RF, and electrical requirements for all the antenna RF, digital and power units, taking into account the available technologies and achievable performance. The antenna design is described for what the main subsystems is concerned, such as RF, power, digital, including mechanical and thermal aspects. Finally the paper reports also a brief description of the most recent development carried out in Canada and in Europe in the last ten years, including the on-going programs.

“…For instance, a waveguide slot array antenna has been employed for TerraSAR-X, the representative German satellite system [6]. Another example is the phased array antenna with a patch-type organic substrate used on the Canadian Radarsat-2 satellite, and the Italian Cosmo-SkyMed satellite [7,8]. Reflector-type antennas have a drawback in their packaging efficiency relative to the waveguide or path array antenna, but they have advantages of high gain, narrow beamwidth, and easy implementation with transmit/receiving modules because of the possibility of a deployable mechanism [9].…”

A procedure for antenna parameter selections is proposed that considers the relationships between synthetic aperture radar performance and the antenna parameters of a parabola-type reflector antenna with a central flat dish. The effects of a central dish designed for weight reduction on the antenna beam pattern are also quantitatively analyzed using commercially available software based on the physical optics algorithm. The results of the theoretical analysis and simulation predict that a larger size of the central dish results in an increase in the sidelobe level, which is the reason for the increase in two important ambiguities, such as range ambiguity ratio (RAR) and azimuth ambiguity ratio (AAR). The dependence of RAR and AAR on Pulse repetition frequency is also analyzed and discussed.
