Photon particles units the light energy and passes through lightweight and sustainable optical fibers, solid medium and/or free space. Photonics is a part of science studies which facilitates several technologies through glowing light. In this survey paper, we particularly focused on a new emerging radar technology known as photonics radar. Based on the technology and applications, the radar is classified as bistatic radar, continuous radar, Doppler radar, monopulse radar, planer array radar, synthetic aperture radar, inverse synthetic aperture radar, ground penetrating radar, walls see-through radar and foliage radar. Due to high power requirements in the pulsed radar particularly for the long distance measurements, the FMCW radar is the best choice. In FMCW radar, the frequency changes/increases in a linear (or stepped, triangular or staircase, etc.) pattern and by calculating the IF frequencies with first-order FFT for range, while the second-order FFT is for Doppler information. Where R is the range, c is the speed of light, and \(\Delta t\) is the time interval. In this paper, the advancement and progression of photonics-based radar communication system accomplishments of the last decades has been shown and also discussions about future study and development of photonics radar have been presented. Photonics radar seemed to be a very intense and bright research study area many practical problems and its wonderful solution have been described here. In this survey repost starting from the historical storyline and basics of photonics radar, the concept of radar based on photonics system and its need, then the digitized PhoDIR system invention, radio frequency signal generation and modulation, beamforming over antenna array and signal transportation, we have discussed the important architecture of photonics radar, phase control process, sampling process, transceiver modules till the radar parameter measurements and various applications of photonics radar including quantum radar. The slow evolution of optics system and how the application has been pushed to radar, microwave and antenna systems have been described here. A comparative study has been presented with the traditional electronics microwave radar systems and photonics radar systems.
This paper has a detailed study of photonics radar and how its components work. Software-defined photonics-based radar must be the near forthcoming next-generation necessities. Photonics-based system came to us as a blessing in science research in this era. Due to the enlarged difficulty of the electronics component for large bandwidth, we had to rely on the delightful photonics system. Photonics is a very vast and distinctive field in recent days. Photonics is a fast and galloping technology related to both microwave and optics science.
