Abstract
The purpose of this thesis is to construct a passive bistatic radar system using two USRP N200 software defined radios and two ordinary TV-antennas. Several auxiliary components were used in order to align and calibrate the devices including an octoclock CDA-2990, switch and signal generator. Several tests were made to verify that the sampling started simultaneously and that no significant phase shift existed between the devices due to the use of different local oscillators. The system is implemented in C++ and the signal processing is done in Matlab making use of the ambiguity function. Measurements were conducted on a commercial aircraft landing at Linköping airport and on an UAV. The results from these measurements show their bistatic... (More)
