A study on adaptive transmit waveform design for bistatic multiple-input multiple-output radar system = 다중안테나를 사용하는 바이스태틱 레이더 시스템에서의 적응적 송신파형 설계에 관한 연구

Ambiguity Function (AF) is well known in radar system as a key tool for determining target resolution capability and presents the nature of the optimal detector. Bistatic configuration play an important role in the shape of the ambiguity function. In general, because the transmitter and the receiver are fixed, position of the target affects the shape of the ambiguity function. In this thesis, we extend the concept of the Range-Velocity Ambiguity Function (RVAF) to replace the traditional ambiguity function in delay-Doppler ambiguity function in order to evaluate the radar system performance. Range resolution and Velocity resolution deduced from the RVAF. Because the shape of RVAF for the Bistatic ULA-MIMO radar is related to position of the target, a new algorithm for adaptively designing the orthogonal Frequency-Hopping waveforms according to the position of the target is used. The simulated annealing (SA) algorithm is suitable for locating a good approximation to the global optimum of a given function in a large search space. We can know that the range resolution and velocity resolution and Integrated Sidelobe Level (ISL) of the matched filter output at the corresponding position of the target from a new algorithm for adaptively designing the orthogonal Frequency-Hopping waveforms.
