It also performs range tracking to keep the radar focused on a single target. Information about the target location is output to displays. Control inputs include operating modes and target selection. 3 is a block diagram of a CW radar. It differs from the pulse radar in that its signal is present all of the time. This means that it must have two antennas, since it must receive a much weaker return signal while it is transmitting. The two antennas must provide sufficient isolation to keep the transmitted signal from saturating the receiver.
Downlink antennas are limited in size because of the size of the UAV airframe and aerodynamic considerations. Therefore, the downlink antennas typically have less gain and more beamwidth than the uplink antennas. 4 Satellite Links Satellite links are important communication signals. They typically operate at microwave frequencies, carrying voice and data over great distances. Most satellites provide simultaneous access to many authorized users, so their signals are many megahertz wide. Some satellites support both commercial and military users.
This type of guidance requires that the platform carrying the illuminator be present (and within line of sight of the target) throughout the engagement. 3 Command Guidance In command guidance, a sensor—usually a radar—tracks a target to predict its path of travel. 7). The weapon has no information about the target location—it just goes where it is commanded. The classic example is a typical surface-to-air guided-missile system. One or more missiles are targeted and guided by a ground-based radar.
