1. A transceiver system of a pulse signal, comprising:
a transmission signal generator configured to generate a transmission signal;
a transceiver configured to
transmit a pulse signal corresponding to the transmission signal; and
receive an echo signal corresponding to the transmission signal from a detection range;
a pulse compression filter configured to compress the echo signal received by the transceiver; and
an echo-stretch filter configured to stretch the compressed echo signal with a group of weight elements being set larger for a center and being set smaller for edge sides in a depth direction.
