Abstract
Phase noise reduction is described for symmetric bistatic radar. In one example, a first beat signal is generated of a second signal received at a first antenna and a third beat signal is generated at a second antenna of a first linear antenna array. A second beat signal is generated of a first signal received at a first antenna of a second linear antenna array. The first beat signal and the third beat signal are multiplied with the complex conjugate of the second beat signal to generate products that are combined to generate a phase estimation correction term that is applied to first and second sets of radar return signals.
