The stepped-FM coded radar realizes a radar profile with excellent freedom from radar mutual interference and high resolution by using the inverse discrete Fourier transform (IDFT) of a part of the broadband transmitted signal and the narrow-band baseband signal obtained by homodyne detection.

✦ Synopsis
In this paper a stepped-FM pulse radar for vehicular collision avoidance is proposed, providing anti-interference capability and high range resolution. Wide-band VCO devices have in general a linearity error over the bandwidth, which is critical issue for high-range-resolution radar. We also suggest a compensation scheme based on the LMS method for the VCO linearity error.

## Abstract This paper presents the optimization of antennas for the collision‐avoidance radar system of an unmanned aerial vehicle (UAV). Geometric parameters and radiation patterns are compared among horn, parabolic, cassegrain, and offset‐cassegrain antennas. Based on the sidelobe levels of the
