Abstract:
1. A radar device, comprising: a transmitter configured to transmit a plurality of transmission pulses per direction to a search area; a radio module configured to receive per direction a plurality of received pulses corresponding to the transmission pulses; a pulse compressor configured to perform pulse compression on the received pulses to generate a range bin data item for each of the received pulses; a Doppler filter processor configured to perform coherent integration on a plurality of range bin data items generated for each direction to generate a range bin data item for each frequency bin; a signal processor configured to generate first data indicating a state of the search area using a range, an azimuth angle, an elevation angle, and a relative velocity calculated based on the frequency bin, based on the range bin data item for each frequency bin obtained by one scan to the search area; an integration processor configured to generate third data by integrating the first data generated at the signal processor with second data generated based on first data obtained by a previous scan to the search area; an estimation module configured to estimate a position at a time of a next scan based on a relative velocity indicated by the third data and shift the third data to the estimated position to generate second data; and a target detector configured to detect a target based on the third data.
