The marine radar is a much bigger subject than is laid out in the article which only skims the surface of the operation and the uses of the radar. As an OOW, it is important to be thorough with the radar and study its operation and features extensively along with the limitations of the...
A primary radar system transmits microwave signals and receives the echo. The system processes the echoes to detect and locate the reflecting target. The working of a basic radar and its basic blocks can be described as shown inFig. 1. In order to measure target information, first, we gener...
Figure 1. An EV-TINYRAD24G block diagram. The blocks will be explained in detail within this article. What Are You Trying to Detect? Before deciding on the frequency of operation or the specific radar topology to be used, it is useful to first deduce some parameters of the object(s) tha...
In addition to the usual measurements of range, angular location, relative velocity, and target track, radar sometimes can obtain information about the size, shape, symmetry, and surface properties of a target. A simple block diagram illustrating the major subsystems of a radar that might be ...
Here,I + jQis the modulated function. The block diagram of optical heterodyning RF generation process is shown in Fig.1. Fig. 1 RF generation by heterodyne process Full size image Directly modulated laser (DML): In this modulation scheme, microwave signals overlap or superimpose with the ...
batteries the power and communication is done over the USB. Maximum current draw of the USB device is 0.5A from 5V. This means that the PA uses about half of the available power. Since other components don't use nearly as much there shouldn't be a problem with USB powered operation. ...

Therefore, in order to determine the influence of a wind turbine on this operation mode, only the blades should be considered. Furthermore, as previously commented, the radial velocity of the blades depends on the rotation angular speed of the blades and on the relative orientation of the ...
The combined LNA and gain block is chosen to provide a total gain of about 30 dB to avoid saturation of the gain block. This is considering that the two antennas present a cross-coupling of about −35 dB within the operation bandwidth and that the target could move very close to the ...
