Switching to a Wide-Angle Multistatic Synthetic Aperture Radar (WAM-SAR) approach allows formation of large high-resolution images. Unfortunately, WAM-SAR suffers from two significant implementation problems. First, wavefront curvature effects, non-linear flight paths, and warped ground planes lead to image defocusing with traditional SAR processing methods. A new 3-D monostatic\/bistatic image formation routine solves the defocusing problem, correcting for all relevant wide-angle effects. Inverse SAR (ISAR) imagery from a Radar Cross Section (RCS) chamber validates this approach. The second implementation problem stems from the large Doppler spread in the wide-angle scene, leading to severe aliasing problems. This research effort develops a new anti-aliasing technique using randomized Stepped-Frequency (SF) waveforms to form Doppler filter nulls coinciding with aliasing artifact locations. Both simulation and laboratory results demonstrate effective performance, eliminating more than 99% of the aliased energy. \u003cbr\u003e\u003c\/p\u003e","brand":"Biblioscholar","offers":[{"title":"Paperback","offer_id":45299003850903,"sku":"9781288409839","price":5180.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9781288409839.webp?v=1767308509","url":"https:\/\/atlanticbooks.com\/products\/wide-angle-multistatic-synthetic-aperture-radar-focused-image-formation-and-aliasing-artifact-mitigation-9781288409839","provider":"Atlantic Books","version":"1.0","type":"link"}
