Title: Radar apparatus
Inventor: NONAKA CHIKAFUSA
IPC: G01S13/10
Filed: 1998-07-24
Abstract: PROBLEM TO BE SOLVED: To obtain a radar apparatus by which a range profile can be acquired in a short time, by a method wherein a transmission signal is transmitted continuously in a burst shape, and also a local oscillation signal which frequency-converts a bursting echo from a target is outputted in a burst shape. SOLUTION: A transmission-frequency setting signal at the timing of a transmission burst signal and a transmission-reception changeover signal are outputted to an oscillation part 6 by a timing generation part 9. A transmission signal in which a transmission frequency signal from the oscillation part 6 is amplified by a transmission part 5 is transmitted to a space from an antenna part 3 via a transmission-reception changeover part 4. Reflected waves from a target which are received by the antenna part 3 are passed through the transmission-reception changeover part 4, a reception part 7 frequency-converts them by a local oscillation signal in the oscillation part 6, and a generated video signal is converted into a digital signal by an A/D conversion part 8. A band synthesis part 10 analyzes the video signal at reverse frequency so as to generate and display a range profile.  At this time, the transmission signal is transmitted in a burst shape, and also the local oscillation signal is output in a burst shape. As result, a plurality of pulse-signals can be transmitted and received at one time.

The content of F/S 63 is checked for a position change in the present picture and the frame store is transported and it is transmitted to F/S 65. The content of F/S 65 is compared with that of a matrix store 11 in a non-matching comparator 67. When they are not matched, they are counted/mapped in a decision circuit 68. Whether the object is spoiled or not is decided in accordance with the counting of non-matching when an inspection cycle completes. A spoil on the object 1 is marked and it passes through a system 69 executing lodging.
