Abstract

We demonstrate that 80 radar pulses within 100 μs, overlapping in temporal and ranging from 500 MHz to 5GHz which covers the UHF band, L band, S band and part of C band, are acquired by an analog-to-digital converter (ADC) with 520MHz bandwidth based on photonic compressive sampling (CS). In the experiment, maximum detection error of 100 KHz is achieved by testing a traditional rectangular pulse and a linear frequency modulated pulse respectively. The overlapping pulse trains are recovered faithfully and an exact waterfall diagram of the recovered signal is obtained, indicating that photonic compressive sampling technique is appealing in the field of radar detection.
