TL;DR: The proposed architecture exploits a single pulsed laser for generating tunable radar signals and receiving their echoes, avoiding radio-frequency up- and downconversion and guaranteeing both the software-defined approach and high resolution.

TL;DR: In this paper, the authors present the first field trial, in a maritime scenario, of a fully coherent multiband radar enabled by the use of photonics, and discuss the potentials for a software-defined radio approach.

TL;DR: In this article, a photonic-based scheme was proposed for generating phase-coded RF pulses suitable for coherent radar systems with pulse compression techniques, which is capable of flexibly generating software-defined phase-modulated RF pulses with high stability, even at very high carrier frequency, using only a single commercial device.

TL;DR: A photonics-based architecture of a multi-band coherent radar system that exploits a single laser unit for the multiband transmitter and receiver sections, reducing the architectural complexity with potential benefits on system dimensions, cost, and reliability is proposed.

TL;DR: The use of photonics in radar systems is leading to a new generation of multifunctional systems that can manage multiple simultaneous coherent radio signals at different frequencies, thus enabling multispectral imaging for advanced surveillance.
