Though inexpensive and reliable, Doppler-only systems have not been widely implemented due to the inherent nonlinear problem of determining a target's position and velocity from their measurements. We solve this problem. In particular, we first establish the lack of observability in the Doppler-only bistatic system, thereby demonstrating the need for multiple transmitters and\/or receivers. Next, for a multistatic system with a sufficient number of transmitter-receiver pairs, we invoke classical optimization techniques, such as gradient-descent and Newton's method, to quickly and reliably find a numerical solution to the system of nonlinear Doppler equations. Finally, we indicate a best design for the transmitter-receiver constellation to be employed in the aforementioned optimization.\u003c\/p\u003e","brand":"Biblioscholar","offers":[{"title":"Paperback","offer_id":46862455505047,"sku":"9781288308279","price":5105.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9781288308279.webp?v=1769966274","url":"https:\/\/atlanticbooks.com\/products\/doppler-only-multistatic-radar-9781288308279","provider":"Atlantic Books","version":"1.0","type":"link"}
