In most cases, the transmitter and receiver of the radar electronics and share is a common antenna. This is called monostatic. Nothing prevents, however, consider a radar system where the transmitter and receiver are separated, a situation called bistatic radar, multistatic configuration or even if you have a separate transmitter and multiple receivers. One other [...]
The radar antenna is mounted on a lateral face of a carrier (airplane or satellite). She has an azimuthally opening large enough (several degrees) in the direction of movement and can move laterally on the horizon to the vertical which gives a fairly low resolution. The return time of echoes is carried out at different [...]
In general, the signal from the transmitter moves in a waveguide in the transmitting antenna. It is however possible to transform the waveguide antenna itself by punching slots. The interference between the various slots are creating a scattering pattern with a strong central peak and secondary peaks lower in the direction along which the slots [...]
Patch (Planar) antennas are used when one wants to reduce the footprint of an antenna, including its height above a ground plane, such transceivers, portable radio, the GPS receivers; planar antennas are used in networking Wi-Fi in amateur radio and in numerous communications professional. The patch antenna is an active networking technologies for the realization [...]
Another method used to disseminate the radar is the antenna phase control network. In this system, we divide the waveguide from the transmitter into a very large number of sub-waveguides. They are each terminating in a slot on a plate facing one direction. By controlling the phase of the wave passing through each of these [...]
