What are the two main types of radar systems?

The two main types of radar systems are indeed continuous wave (CW) radar and pulsed radar.

Continuous wave radar operates by transmitting a constant wave of energy and receiving the reflected signals continuously. This method allows for the detection of moving targets through the Doppler effect, as the frequency of the returned signal will change based on the relative speed of the target. Due to its design, CW radar is typically used for speed detection applications, as it provides consistent and real-time data.

Pulsed radar, on the other hand, transmits energy in short bursts (or pulses) followed by periods of silence as it waits for echoes from the reflected wave. This system allows for better distance measurement, as it calculates the time it takes for the pulse to return, providing information about the distance to the target. Pulsed radar is widely utilized in many applications, including air traffic control and meteorology, where determining the distance to targets is essential.

The choice indicating these two types of radar systems captures the fundamental operational principles that distinguish them. Understanding these distinctions helps in comprehending how various radar systems function in different applications.
