Description
CubeSat-borne radar has many potential applications in space exploration including tracking, imaging, and weather prediction. A continuous-waveform radar has advantages of compact size and low power consumption, making it suitable to implement on small platforms such as CubeSats. This paper demonstrates an isolation technique that overcomes the self-interference between the transmit and receive antennas inherent to continuous-waveform radar. The presented approach combines opposite circularly polarized antennas on two deployed solar panels to minimize the self-interference. The prototype antennas are tested on a 6U CubeSat frame and the results show more than 40 dB isolation, satisfying the power budget requirements.
