Pulse radar device and operating method thereof

A pulse radar device comprising:

• a clock generator configured to output a transmission clock signal, and to output a reception clock signal by delaying the transmission clock signal by a clock delay value;
• a transmitter configured to generate and radiate a transmission pulse based on the transmission clock signal;
• a memory including:
• a first memory configured to store a previously generated scan vector and to operate in a read mode during a current scan period;
• and
• a second memory configured to store a representative scan vector and to operate in a write mode during the current scan period;
• and
• a receiver configured to accept the reception clock signal from the clock generator, to receive echo pulses reflected from a target through a reception antenna based on the reception clock signal;
• wherein the receiver comprises an operator configured to:
• while receiving echo pulses corresponding to a current scan period,
• reference the scan vector stored in the first memory operating in the read mode,
• perform a computation using the referenced scan vector and data derived from the received echo pulses before completion of storage of the received echo pulses, and
• store a result of the computation as the representative scan vector in the second memory operating in the write mode,
• wherein the first memory and the second memory use identical address values, and
• wherein, in a subsequent scan period, the second memory operates in the read mode and the first memory operates in the write mode by exchanging operational roles of the first memory and the second memory.
