| 摘 要： | 将三重相关峰值检测技术用于对红外探测系统亚像元或点目标图像的信号处理。研究表明，该技术在峰值信噪比为０．８、功率信噪比为－９．７３ｄＢ时可获得的信噪比改善约为２３ｄＢ。提出了一种可供实用的三重相关的二维图形表示法，该方法在峰值信噪比低至０．４８、功率信噪比低至－１４．２ｄＢ时仍可以从噪声中有效地提取点目标信号的幅度信息。

| Abstract: | Triple correlation peak inspecting technique (TCPIT) was adopted for the signal processing of IR systems in detecting sub pixels or point targets. Investigations show that the signal to noise ratio (SNR) can be improved by about 23dB with the input peak SNR of 0.84 and the input power SNR of -9.73dB. The 2 D graphics method for implementation of TCPIT was recommended. Using this approach,the amplitude information of point targets can be still effectively extracted from noises with the input peak SNR lowered to 0.48 and the input power SNR lowered to -14.24dB. |
