<p><P>PROBLEM TO BE SOLVED: To improve detection capability of a target without causing increase in device scale. <P>SOLUTION: The radar signal processing device includes: a transmission antenna 2a radiating a transmission wave; a reception antenna 2b receiving a reflected wave obtained by the reflection of the transmission wave at the object; an A/D conversion part 3 converting a reception signal to digital data; a memory part 4 temporally storing the digital data; an integration part 5 reading the digital data stored in the memory part 4 for each preset distance range of the target detection and integrating the digital data by using fixed-point calculation of a fixed bit length; a detection part 6 detecting a peak position from the data obtained by the integration; a specification calculation part 7 calculating the specifications of the target from the data obtained by the integration and a detected peak position; and a distance adjustment part 8 adjusting the amount of bit shift of a fixed bit length of integration part 5 for each distance range. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
