What is signal processing in radar?
What is signal processing in radar?
The signal processor is that part of the system which separates targets from clutter on the basis of Doppler content and amplitude characteristics. In modern radar sets the conversion of radar signals to digital form is typically accomplished after IF amplification and phase sensitive detection.
Which circuit is used in the radar signal processing?
A range gate is an electronic circuit that selects signals within a given time period; the “gate” allows signals to pass through only within the selected time. The term is mostly used in radar, where range gates are used to select certain targets for further processing.
How is a radar signal generated?
Radar signal A radar system has a transmitter that emits radio waves known as radar signals in predetermined directions. When these signals contact an object they are usually reflected or scattered in many directions, although some of them will be absorbed and penetrate into the target.
What is the role of DSP in radar signal processing?
At the transmitter end, it generates and shapes the transmission pulses, controls the antenna beam pattern while at the receiver, DSP performs many complex tasks, including STAP (space time adaptive processing) – the removal of clutter, and beamforming (electronic guidance of direction).
How many types of radars are there?
two types
Radars can be classified into the following two types based on the type of signal with which Radar can be operated. Now, let us discuss about these two types of Radars one by one.
What is a range gate in radar?
A selectable interval of range (or of time delay from transmission) within which returning radar signals are measured. Gating is used to isolate the echoes from different regions of distributed targets.
What are the components of radar?
There are four basic elements in any functional radar: transmitter, antenna, receiver, and indicator.
