RADAR DEVICE

摘要

PROBLEM TO BE SOLVED: To prevent the deterioration of target detecting performance when an acceleration target is existed in the receiving signal of a radar. SOLUTION: A receiving signal received by a receiving antenna 1 is divided into respective frequency spectral in a coherent integral circuit 7 and amplitude is detected in an amplitude detecting circuit 8. An acceleration compensation set circuit 10 sets an acceleration and an integral path over Doppler cell of a plurality of frequency bands is set based on this acceleration. A cell of the receiving signal on this integral path is provided to an acceleration compensation integral circuit 11. The acceleration compensation integral circuit 11 performs coherent integration by finding the sum of the inputted cell. Incoherent integral result for a plurality of acceleration and a plurality of initial cells are stored in a memory circuit 12 and a termination determining circuit 13 and a target is finally detected by a target detecting circuit 15 and alarming is performed by an alarm circuit 16.
