<p><P>PROBLEM TO BE SOLVED: To perform easy detection and follow-up including initial detection even in the case that a moving target difficult to detect exists in a blind speed region when detecting a follow-up target with MTI processing. <P>SOLUTION: A video integration processing system is used for searching and scanning operation to detect a target, and an MTI processing system is used for follow-up scanning operation. After the plot generating processing of video signals from the processing systems and the calculation of the predicting position and the speed of the target, a target information creating/managing part extracts a target having a speed exceeding a threshold value, as a follow-up object target, to create target information, and extracts the object target having a speed which falls in the blind speed region, and a follow-up PRF calculating part calculates the Doppler frequency of the speed of the object target and calculating a value for a half or so the Doppler frequency as the transmission PRF of a follow-up beam to be given to an excitation receiving part. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
