“…Similar disadvantages arise with systems based on camera vision. However, one approach that has proved to work for robotic applications is the use of various radar systems to aid navigation [22,23]. With this in mind, as well as our own experience with marine radar, we propose here a system based on the use of automotive radar for ASV navigation and anti-collision purposes.…”

Autonomous surface vehicles (ASVs) are becoming more and more popular for performing hydrographic and navigational tasks. One of the key aspects of autonomous navigation is the need to avoid collisions with other objects, including shore structures. During a mission, an ASV should be able to automatically detect obstacles and perform suitable maneuvers. This situation also arises in near-coastal areas, where shore structures like berths or moored vessels can be encountered. On the other hand, detection of coastal structures may also be helpful for berthing operations. An ASV can be launched and moored automatically only if it can detect obstacles in its vicinity. One commonly used method for target detection by ASVs involves the use of laser rangefinders. The main disadvantage of this approach is that such systems perform poorly in conditions with bad visibility, such as in fog or heavy rain. Therefore, alternative methods need to be sought. An innovative approach to this task is presented in this paper, which describes the use of automotive three-dimensional radar on a floating platform. The goal of the study was to assess target detection possibilities based on a comparison with photogrammetric images obtained by an unmanned aerial vehicle (UAV). The scenarios considered focused on analyzing the possibility of detecting shore structures like berths, wooden jetties, and small houses, as well as natural objects like trees or other kinds of vegetation. The recording from the radar was integrated into a single complex radar image of shore targets. It was then compared with an orthophotomap prepared from AUV camera pictures, as well as with a map based on traditional land surveys. The possibility and accuracy of detection for various types of shore structure were statistically assessed. The results show good potential for the proposed approach—in general, objects can be detected using the radar—although there is a need for development of further signal processing algorithms.

This article presents a hybrid digital and RF front‐end module (FEM) of a 24‐GHz pulse‐Doppler radar system for intelligent transport system applications. The conventional pulse generators use analog components such as step recovery diode. It is difficult to control the parameters of the pulse. In addition, the heterodyne architecture based transceivers show good performance, but they are very expensive. To overcome these limitations, a digital pulse generator was developed based on field‐programmable gate array platform to obtain high degree of freedom in a waveform design. Instead of the heterodyne architecture, a transceiver based on the homodyne architecture was developed. For the first time, hybrid digital FEM based 24‐GHz pulse‐Doppler radar was developed by combining a digital pulse generator and a homodyne‐based transceiver. Experimental results showed the feasibility of using a hybrid digital FEM for a 24‐GHz pulse‐Doppler radar. The developed hybrid digital FEM contributes to the advancement of the digital radar field. © 2013 Wiley Periodicals, Inc.

“…During the past 2 decades, millimeter wave radar systems operating in FMCW mode have been intensively developed for a variety of applications such as collision avoidance in automobile [1][2][3], remote sensing [4,5], concealed weapon detection for homeland security needs [6][7][8] and other related areas. The choice of operating frequency is the critical issue in design FMCW systems and greatly depends on penetration depth through various materials.…”

A single-pixel imaging remote sensor operating at 330 GHz is described. It is based on a frequency modulated continuous wave (FMCW) and aimed at detection of concealed objects for ranges up to 40 m. The system consists of 2 horn-lens antennas integrated with a homodyne transceiver. The synthesized linear FMCW signal at X-band is multiplied by a factor of 32 to generate the transmitted signal. An intermediate frequency (IF) signal obtained in the output port of the 2-nd harmonic mixer is employed for image processing. Distance measurements were made by performing data acquisition unit based on LabView interface and resulting in a range resolution about 1 cm. Examples of 2D and 3D images reconstructed with this sensor are presented.
