RCS Measurement Based on Frequency-sparse 3-D Imaging
In the image-based radar cross-section (RCS) measurement system, wide-band transmitter and receiver are complex and expensive. To overcome this problem, this paper proposes a new method of frequency-sparse 3-D imaging. By increasing frequency interval, the number of sweep points is reduced. An improved 3-D back project (BP) algorithm is presented to obtain the image of targets, finally, the RCS of targets can be calculated. Simulation results show that this method is effective when the number of sweep points is adequate.
