1. A pulse radar apparatus comprising:
a clock generator which generates a transmission clock signal, a reception clock signal, and a sensitivity adjustment interval signal;
a transmitter which radiates a transmission pulse based on the transmission clock signal; and
a receiver which receives a first pulse and a second pulse, which are associated with the transmission pulse, with different sensitivities based on the reception clock signal and the sensitivity adjustment interval signal;
wherein the clock generator
generates a minimum detection range signal corresponding to a minimum transmission/reception clock delay time, which is an interval between the transmission clock signal and the reception clock signal and which is at a minimum value; and
controls the sensitivity adjustment interval signal during a sensitivity adjustment interval after a delay offset from a point in time when the minimum detection range signal is generated,
wherein a sensitivity of the receiver decreases during the sensitivity adjustment interval in response to the sensitivity adjustment interval signal, and
wherein the sensitivity adjustment interval corresponds to a time interval in which the pulse radar apparatus receives a pulse in which the transmission pulse is reflected from a first object located between the pulse radar device and a second object.
