Abstract :
This paper extends previous work to process and combine data from multiple bistatic pairs in a passive multistatic radar system. The previously presented Multistatic Velocity Backprojection (MVBP) combines and visualizes multistatic radar data. MVBP generates a six-dimensional data cube in position and velocity but does not provide a mechanism for detecting targets within the space. This paper discusses Detection Aided Multistatic Velocity Backprojection (DA-MVBP), a method for seeding MVBP with detections from individual bistatic pairs. DA-MVBP reduces the space through which it is necessary to search for targets in backprojected multistatic radar data and may result in enhanced parameter estimation and detection performance over traditional multilateration of detections. In this work DA-MVBP is applied to experimental passive multistatic radar data.
