The principle of operation of pulse radar is based on time separation between the transmitted and reflected signal and measurement of the time interval between transmitted and received pulses. In FM radar, because continuous radiation is used, separation of transmitted and reflected signals in time is impossible. Hence, reception of information about the range to [...]

Dynamic Range
The radar receiver must be capable of handling large signals from surface reflections and short-range targets and also detect small signals near the noise floor. The ratio of the largest receivable signal to the minimal detectable signal is called the dynamic range and is defined as follows:
