This paper mainly introduces the application of non-acoustic antisubmarine detection technology in trailing detection of submarine by aerial platform. The characteristics of submarine trailing are presented,including track trailing,bubble trailing,thermal trailing,biology trailing,and magnetic trailing.According to their different characteristics,such non-acoustic detection technologies as SAR,laser radar,infrared radiation temperature measurement technology,hyper-spectral imaging and low-frequency magnetic anomaly detection technology are introduced.Analysis is made to the advantages and disadvantages of these non-acoustic technologies for submarine detection,and their potential application on aerial platform.Finally,expectation is made to the future application of the non-acoustic technologies in aviation antisubmarine of trailing detection.
