Several classes of daughterboard modules exist: Receivers, Transmitters and Transceivers. Transmitter daughterboard modules can modulate an output signal to a higher frequency; Receiver daughterboard modules can acquire an RF signal and convert it to baseband; Transceiver daughterboard modules combine the functionality of a Transmitter and ...
The receiver's gain is automatically adjusted to maintain a constant level of overall visible clutter. While this does not help detect targets masked by stronger surrounding clutter, it does help to distinguish strong target sources. In the past, radar AGC was electronically controlled and affected the gain of the entire radar receiver.

GNSS receivers are sold as portable devices, and are also incorporated in cell phones, vehicles and weapons, even artillery shells. VOR receiver - navigational instrument on an aircraft that uses the VHF signal from VOR navigational beacons between 108 and 117.95 MHz to determine the direction to the beacon very accurately, for air navigation.
Software-defined radio (SDR) is a radio communication system where components that conventionally have been implemented in analog hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) are instead implemented by means of software on a computer or embedded system. [1]
An Icom IC-R5 hand-held scanner A GMRS radio that also has scanning capabilities. A radio scanner or simply scanner is a radio receiver that can automatically tune discrete frequencies, scanning over a frequency band to find a signal until the initial transmission ceases.
This is the problem that track while scan is meant to address. In traditional radar systems, the display is purely electrical; signals from the radar dish are amplified and sent directly to an oscilloscope for display. There is a one-to-one correspondence between "blips" on the display and a radio signal being received from the antenna.
The difference between the models is largely to the degrees of freedom and the general layout of the target. The first four of these models were considered in Swerling's original paper, and are referred to as models I through IV. The V model, also referred to as the 0 model, is the degenerate case with an infinite number of degrees of freedom.
