1. A radar signal processing device comprising:
processing circuitry configured to:
generate a processing signal based on a beat signal of a transmission signal and a reception signal,
generate a plurality of extracted beat signals by applying a plurality of window functions on the processing signal,
convert the plurality of extracted beat signals to amplitude data indicating a relationship between a distance and an amplitude, and
integrate a plurality of the amplitude data into integrated data, wherein
a first window function and a second window function of the plurality of window functions do not overlap in time,
a third window function of the plurality of window functions overlaps at least one of the first window function and the second window function,
peaks of window weights of the first window function, the second window function, and the third window function are at different times, and
the peak of the window weight of the third window function is between the peaks of window weights of the first window function and the second window function.
