pulzusradarkoncepció
A pulzusradarkoncepció, often translated as pulsed radar concept, refers to the fundamental operating principle of many radar systems. In this approach, a radar transmitter generates short, high-power bursts of electromagnetic energy, known as pulses. These pulses are then transmitted into the environment. When a pulse encounters an object, a portion of its energy is reflected back towards the radar receiver. The radar measures the time it takes for the reflected pulse, or echo, to return. Knowing the speed of electromagnetic waves (the speed of light), this time difference can be used to calculate the distance to the object. The repetition rate of these transmitted pulses, known as the pulse repetition frequency (PRF), determines how frequently the radar can measure the range to an object and influences the maximum unambiguous range that can be detected. By analyzing the characteristics of the returning echo, such as its strength and frequency shift (Doppler effect), additional information about the target, such as its velocity and size, can be inferred. This pulsed transmission and echo reception is the core mechanism by which pulsed radar systems detect and track targets.
