To improve the sensitivity of the infrared remote sensing system, an innovative design about acquisition, transmission and display imaging system is described based on 320×256 CMOS infrared sensor as imaging acquisition chip. This paper presents a detailed analysis about the influence of the digital TDI to system SNR and a logical design of digital TDI implemented based on FPGA. The experiment result demonstrates the imaging system grounded on digital TDI technology achieves an excellent SNR characteristic and a good image quality.
