Radar is an important sensing technology for three-dimensional positioning of aircraft. This method requires detecting the response from the object to the signal transmitted from the antenna, but the accuracy becomes unstable due to effects such as o

In this study, we experimentally proved the relationship between the number of subapertures and the self-focusing effect of a polarization-inverted transmitter by up-chirp signal driving. First, experiments on the focusing effect by aperture division

In November 2016 in Uchiura Bay, the third sea trial of ambient noise imaging with an acoustic lens was carried out to detect two targets having frequency response peaks of 80 and 160 kHz. Here, the received frequency band was divided into three part
