Abstract:

The performance of the selected bands in stealth aircraft target multi-spectral detection is hard to analyze and evaluate. A unit energy spectrum detection system is designed to analyze the selected detection band, demonstrating the availability of the selected detection bands. The selected narrow band receives less energy than the traditional wide band, while the signal itself can not represent the performance of target detection. By analyzing the unit energy spectrum detection principle and considering the alternative model of the system signal, the model of the wave quality factor is established to objectively analyze the performance of the selected band in different visibilities, cloud backgrounds and detection ranges. The result shows that the unit energy detection system can analyze each band detection objectively and accurately. At the same time, it also gives a clear and intuitive display of the jitter property while using it in different cloud backgrounds, proving that the detection effect of the narrow band is superior to the wide band and consistent with the theoretical study.

Key words: multi-spectral band, wave quality factor, spectrum detection, stealth target
