In this paper a bistatic Multiple Input Multiple Output (MIMO) ground based air surveillance radar system is designed for a maximum target range of 150 kilometers from the transmitter and 175 kilometers from the receiver , a range resolution of 7.5m, the overall detection rate is 90% and the False alarm rate ( FAR) = 1e-6. The radar operating frequency is 10 gigahertz. The design focuses on implementation of angle estimation and the effects of antenna placement on angle estimation performance. Most literatures on bistatic MIMO radar systems assume equal transmit and and receive antenna elements with half wavelength inter element spacing for both arrays. An antenna placement scheme for varying the number of transmit and receive antenna for good angle estimation performance is proposed. Matlab simulations were performed to evaluate the performance of the proposed method.
