TRIPLE CORRELATION PEAK INSPECTING TECHNIQUE IN IR DETECTION SYSTEMS

Triple correlation peak inspecting technique (TCPIT) was adopted for t he signal processing of IR systems in detecting sub-pixels or point ta rgets. 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 df TC PIT 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.
