Amit Agarwal, Debasish Bhaskar, Rabindranath Bera . Distinction of Closely Spaced Targets using Pseudo Resolution Technique. International Journal of Computer Applications. 38, 7 ( January 2012), 45-54. DOI=10.5120/4704-6863
Abstract
The radar range resolution depends on signal bandwidth thereby detection of multiple closely spaced scattered points depends on bandwidth. To resolve this method of pseudo resolution is introduced which exploits the bandwidth allocation and increases the resolution of the overlapping scattered point (target/multipath). This resolution can be achieved by increasing the bandwidth of the received signal at receiver by stuffing zeros in between the samples received. This is why such bandwidth allocation is referred to as virtual bandwidth. The entire method is called Pseudo resolution.
