Abstract

This paper describes the design and implementation of a software defined phased radar receiver array developed for MIT Lincoln Laboratory. This receiver array was constructed with the USRP2, an inexpensive software defined radio to allow for scalability to larger receiver arrays. The team worked closely with Lincoln Laboratory staff to conduct time synchronization testing between the receivers in the array in order to characterize the internal oscillator drift of the radios. The team was able to get the receiver array synchronized within less than 2 ns. In addition to building the array, the team implemented radar processing algorithms in Matlab which had the ability to detect a target's range, radial velocity and direction from the receiver with an angular resolution of 20 degrees.
