How are radar signals processed?
Radar signals are processed through a series of steps that include transmission, reception and analysis. Transmitted radio waves are sent in pulses, which travel through the air until they strike an object and reflect back to the radar receiver. The receiver captures these returned signals and signal processing techniques are applied to filter out the noise, amplify the signal and extract relevant information such as range, speed and direction of the target.
The steps in radar signal processing typically involve the following:
Pulse transmission: The radar system generates and emits pulses of radio waves.
Signal reflection: Pulses travel through the air, reflect off objects and return to the radar receiver.
Signal reception: The radar receiver captures the returned signals.
Amplification: The returned signals are amplified to make them easier to analyze.
Filtering: noise and unwanted signals are filtered.
What are the steps of radar signal processing?
Detection: The presence of a target is detected.

Range measurement: The delay between transmission and reception is used to calculate the distance to the target.
Doppler processing: frequency shifts in the returned signal are analyzed to determine the speed of the target.
Data display: Processed information is displayed on a screen for interpretation.
A radar signal is generated by a transmitter that produces high frequency radio waves. These waves are shaped into bursts or short pulses, then emitted by an antenna. The antenna directs the pulses into the environment, where they travel until they encounter an object and are reflected. Generating these pulses involves oscillators, amplifiers, and modulators in the radar system, which work together to create the precise frequency and duration of the transmitted signal.
