目標検知装置、目標推定方法およびプログラム
Document Type and Number:
Japanese Patent JP7299601
Kind Code:
B2
Abstract:
To enable a plurality of targets to be detected with high accuracy in a radar.SOLUTION: The present invention performs processing with regard to distance direction information from a received signal obtained by receiving a reflected wave of a transmit signal, and thereby acquires a multi-dimension signal having a dimension in the distance direction (fast time direction) and another dimension in at least one of a pulse bit direction, a frequency direction and an antenna element direction (slow time direction). Then, a signal of at least one or more dimensions, except the distance direction dimension, of the multi-dimension signal is processed, and at least one of a target seed, a target distance and an angle is detected from the processed signal. Furthermore, a signal complex amplitude per distance bin is obtained from the detected target, a subtraction signal is generated on the basis of the detected target information and the signal complex amplitude per distance bin, and the generated subtraction signal is subtracted from the multi-dimension signal to detect another target.SELECTED DRAWING: Figure 1
