1. A target detection device, comprising:
a transmission array comprising a plurality of transmission elements configured to convert an electric signal into a transmission wave; and
a signal generator configured to generate a plurality of sets of electric signals including a first set of electric signals and a second set of electric signals different from the first set, each set being generated with different phase settings, wherein
the signal generator is configured to:
group the plurality of transmission elements according to a plurality of grouping configurations including a first grouping configuration and a second grouping configuration, in the first grouping configuration, the plurality of transmission elements being grouped into a plurality of groups each having p transmission elements, and, in the second grouping configuration, the plurality of transmission elements being grouped into a plurality of groups each having q transmission elements, said q being different from said p,
input the first set of electric signals to each group of the first grouping configuration, and
input the second set of electric signals to each group of the second grouping configuration,

wherein the plurality of transmission elements used in the first grouping configuration and the plurality of transmission elements used in the second grouping configuration are the same.
