Over the past few years, we have been continually upgrading and testing an acousto-optic (AO) multichannel adaptive optical processor, the anti-jamming optical beam-nuller (AJOB), with the ultimate goal of mitigating multipath jamming interference in advanced surveillance applications. Multipath signal considerations are often crucial to successful operation and utilization of adaptive interference cancellation radar hardware. Relative time of arrival and signal strength detection are necessary for accurate placement of the necessary nulls. Presented in this paper are the initial test results and the preliminary test plans for conducting simulated multipath jamming cancellation. Thus, the AJOB represents a potential solution to the problem of multisource multipath jamming interference. |
