Cross-correlation detection and time difference estimation in non-cooperative bistatic radar systems

In this paper, the basic geometrical relationship and signal energy relationship of non-cooperative bistatic radar are introduced, and the method using the cross-correlation to obtain the time difference of direct signals and target scattering echoes in noisy environment is discussed. Some experiments have been done to simulate the process of cross-correlation detection and time difference estimation. What's more, on the basis of them, some parameters affecting the performance of the algorithm, such as the signal-noise ratio, pulse width and pulse number of cross-correlation, are analyzed by Monte Carlo simulation.
