1. A radar apparatus comprising:
a plurality of integrated circuitries, which, in operation, perform signal processing on a received signal; and
signal processing circuitry, which, in operation, compensates for a deviation between the plurality of integrated circuitries,
wherein the signal processing circuitry, which, in operation, compensates the deviation between one integrated circuitry of the plurality of integrated circuitries and remaining integrated circuitries of the plurality of integrated circuitries with reference to leak radio wave components received by receive antennas connected to the one integrated circuitry of the plurality of integrated circuitries.
