A light weight SAR, suitable for use on short range tactical UAV, has been designed and built. The system consists of a fully digital receive array, and a very compact active transmit antenna. The approximate weight of the complete system is 6 kg, with power consumption below 75 W, depending on the required data acquisition volume. This X-band system is designed to provide an image resolution down to 10-15 cm at a maximum range of approximately 5 km. The design is described, and initial ground test results are presented.
