## Abstract

Of the many applications of bistatic (BS) radars, this paper addresses the possibility to replace a monostatic radar with its highly directive antenna, by a coherent BS radar using a single short baseline between the transmitter and the receiver, and no direction measurements. The method applies to a moving target and requires both <italic>range</italic> and <italic>range-rate</italic> BS measurements. Theory and field-test results demonstrate, on a two-dimensional scene, how several consecutive pairs of BS <italic>range</italic> <inline-formula><tex-math notation="LaTeX">$( r )$</tex-math></inline-formula> and <italic>range-rate</italic> <inline-formula><tex-math notation="LaTeX">$( {\dot{r}} )$</tex-math></inline-formula> measurements of a moving target can provide the target's position, velocity and heading (<italic>x, y, v_{x}, v_{y}</italic>). In a three-dimensional scene, with 5 estimated target parameters (<italic>x, y, h, v_{x}, v_{y}</italic>), a second receiver is needed, not in-line with the original baseline. The <inline-formula><tex-math notation="LaTeX">$( {r,\dot{r}} )$</tex-math></inline-formula> measurements distinguish the suggested concept from most other multistatic radars as well as the well-known multilateration positioning or interferometric angle-of-arrival estimation.
