Abstract

We present the continuing development of an anti-jamming optical beamformer (AJOB) at Rome Laboratory's Photonics Division. Developments include live radar tests and new system designs. The purpose of the AJOB system is the cancellation of multipath jamming interference in advanced surveillance radars. AJOB is a multichannel adaptive optical system which performs cancellation of multiple wideband (10 MHz) interference sources in the presence of multipath. The live radar test consisted of using a downconverted 80 MHz received signal from the main and subarrays of a C-band radar to correlate jamming signals produced by stationary jammers. The correlation parameters fed a tapped delay line filter to form an estimate of the noise, which was subtracted from the main antenna signal. For the scenarios tested, the long integration time for the correlation data provided accurate estimates of the jammer delays, and therefore single-step convergence was achieved.
