Test of X-band AutoSAR Using Measurement Instruments

Abstract

We introduce the stripmap mode test of X-band AutoSAR (automobile synthetic aperture radar) prototype in this paper. We design and develop a power amplifier, a signal demodulator, and use Matlab for post-processing. The transmitter of this prototype, however composes measurement instruments, an Arbitrary Waveform Generator (N8241A, Keysight) for chirp generation and a Vector Signal Generator (E8267D, Keysight) for modulation. Moreover, the COTS (Commercial-Off-The-Shelf) is used for data recording in this test. The resolutions of the prototype finally are 0.41 m range, 0.14 m azimuth.
