DETECTION FOR HIGH-RESOLUTION RADARS

In this paper we discuss detection problems for a high resolution rada r. Fluctuation in the target radar cross section usually decreases the probability of detection. However, through integration of cells withi n range profiles of a high resolution radar, variation of the integrat ed magnitude with respect to the change of carrier frequency and targe t aspect becomes much smaller, and this is helpful for improving the p robability of detection. Two detection algorithms, the cell integratio n method and the correlation method, for a high resolution radar are p roposed, and their detection performances are compared with that obtai ned by a conventional low resolution radar. Some theoretical formulati ons are developed. Simulation results show the effectiveness of the pr oposed algorithms.
