This thesis focuses on the construction and application of a ground based radar for monitoring slowly moving target surfaces such as unstable rock slopes. The radar is given the name GBSAR (Ground Based interferometric Synthetic Aperture Radar). We first describe situations where usage of this kind of radar technology is appropriate. Given this situation description, a review of other possible sensors are given. All sensors are compared with respect to what kind of information they provide, update frequency, accuracy and limitations. We describe the working principle of the radar and schematic design of the electronics. The electronics can be divided into a frequency synthesis and upconversion part, a receiver and demodulation part and a digital processor part. Calculations of the signal to noise ratio shows that the chosen radar design parameters meets the requirement for interferometric processing. The radar transmits a linear frequency modulated signal which is demodulated in the receiver, digitised and stored for later post-processing. The bandwidth of the radar is 1 GHz.
