This paper studies distributed passive radar imaging of two-dimensional (2-D) scene. The echoes and the reflectivity of target are confirmed to be a Fourier transform pair. However, due to the space configuration based on the illuminators of opportunity, the echoes are sampled non-uniformly, which lead to the non-equispaced property of space-spectrum distribution. In this case, direct 2-D FFT reconstruction...
This paper studies the distributed passive radar three-dimensional (3-D) imaging under the 3-D configuration formed by the illuminators of opportunity and the distributed receivers. The echoes received by the distributed channels actually constitute the target wavenumber-domain coverage, whose characteristics such as range, uniformity and compactness greatly affect the inversion performance. Generally,...
