    Abstract

    The detection of the aerial targets applied on the space-based platform has disadvantages of long distance, weak signal of targets, complex background clutters and detector noises. Therefore, to obtain the strongest signal of the target, it is crucial to determine the bands used during the process of detection. The trapezoidal plume and the cone plume simulation model are systematically established, meanwhile an SNCR method combining the signal to noisy ratio(SNR) and the signal to clutter ratio(SCR) is proposed to determine the detection bands. The experimental result shows that, different aerial targets have different SNCR values, but with the same peak value. According to the method mentioned above, bands have been determined and eventually the values are as follows:3.7~4.15 μm in MWIR band in which interval is not less than 0.3 μm8~12 μm in LWIR band in which interval is not less than 0.3 μm.
