store a single pulse of the received signal for exactly the time between broadcasts (the pulse repetition frequency). This stored pulse will be sent to...

Frequency ambiguity resolution is used to find the true target velocity for medium pulse repetition frequency (PRF) radar systems. This is used with pulse-Doppler...

moving or stationary objects. Transmit pulses are sent at the pulse repetition frequency. Energy from the transmit pulses propagate through space until they...

electromagnetic pulse is a short surge of electromagnetic energy. Its short duration means that it will be spread over a range of frequencies. Pulses are typically...

longer times between pulses should be used, referred to as a pulse repetition time, or its reciprocal, pulse repetition frequency. These two effects tend...
