Radar signal processing steps typically include pulse compression, moving target indication (MTI), Doppler filtering, detection and tracking. Pulse compression improves range resolution by narrowing the pulse width. MTI removes stationary objects from the radar display, highlighting moving targets. Doppler filtering separates targets based on their relative velocities. Detection consists of identifying potential targets by comparing received signals to a threshold.
Tracking maintains the position, speed and trajectory of identified targets over time.
Signal processing steps typically involve filtering, sampling, quantification, transformation, and analysis. Filtering removes unwanted noise and interference. Sampling converts the continuous signal into a discrete form for digital processing. Quantization maps sampled values into a finite range of levels. The transformation, like the Fourier transform, converts the signal to a different domain (for example, time to frequency).
Analytics interprets transformed data to extract useful information or detect patterns.
Signal processing of a radar system involves generating the transmitted waveform, receiving and filtering the returned echoes, and applying algorithms to detect and track targets. This process begins with pulse generation and transmission, followed by reception of reflected signals from targets. The received signals are then amplified, filtered and digitized.
Various signal processing techniques, such as pulse compression and Doppler processing, are applied to extract target information, which is then used for detection and tracking.
The radar works step by step by first transmitting a pulse or continuous wave signal to a target area. When the signal hits an object, it reflects back to the radar receiver. The radar system measures the delay between signal transmission and reception to calculate the distance to the target. Doppler shifts in the returned signal provide information about the speed of the target.
Signal processing techniques are then applied to filter, detect and track the target based on the received echoes.
The radar process involves several key steps: transmission, reflection, reception and processing. Transmission involves sending an electromagnetic signal. Reflection occurs when the signal bounces off objects in its path. Reception involves capturing the signals reflected back to the radar receiver. Processing includes amplification and filtering of received signals, followed by application of various signal processing algorithms to detect, identify and track targets
