Space-Doppler processing for multichannel ISAR imaging of non-cooperative targets embedded in strong clutter

Space‐Doppler adaptive processing for radar imaging of moving targets masked by ground clutter

“…This operation performs both cross-range compression at each channel via single channel RD and the summation of the P complex images as described above [26]. It is obvious then, that all the remarks about the phase term K (p) 0 and the consequent distortion term J(y 1 ) should be considered.…”

“…A sub-optimum processing scheme is described in [26] which allows for the reduction of the amount of training data needed to estimate the cross-power spectral matrix. In this approach, the Doppler spectrum is split into adjacent frequency bands of length L and the SDAP is carried out using only the L Doppler bins within each band.…”

“…The joint SDAP–ISAR processing was first introduced in [26] and, for the sake of clarity, will be briefly reviewed here. Its difference with respect to the STAP‐ISAR and its derivatives approaches discussed in [25] will be examined.…”

“…In this paper, an alternative to STAP and its derivatives its proposed. The new approach, originally presented in [26], is termed space‐Doppler adaptive processing (SDAP) as its formulation is derived from a careful consideration of the range Doppler (RD) image formation algorithm used in ISAR processing. This model is formulated in the space/Doppler domain and, because of the RD specific features, is structurally and algorithmically different from STAP techniques implemented in the Doppler domain, that is, the class of post‐Doppler STAP algorithms discussed in [27].…”
