Development of radio telescope receiver based on GNU radio and USRP

This paper presents the development of radio telescope receiver based on GNU radio and Universal Software Radio Peripheral (USRP). Usually an existing radio telescope receiver is only able to be used for fixed frequency and signal processing system; hence the other different frequency receiver needs to be carried out with different types of observation. Here, the development of radio telescope receiver includes the hardware system and the signal processing system. Then, the design of radio telescope receiver is developed based on GNU Radio and implemented by using USRP. From the result, it shows that the implemented radio telescope receiver which is applied for continuum observation can clearly detect signals at frequencies of 322MHz and 406MHz n which those frequencies are usually used in radio telescope.
