A signal processing device according to an embodiment includes a plurality of signal processing units and a pseudo signal generating unit. The plurality of signal processing units are provided in a plurality of reception antennas which receive reflection signals of a transmission signal reflected on an object, and perform signal processing in parallel on beat signals which are generated based on the transmission signal and the reflections signals. The pseudo signal generating unit generates a pseudo signal imitating the beat signal, and inputs the pseudo signal as a target of the signal processing into the plurality of signal processing units in parallel.

A signal processor includes an amplifier that amplifies a control signal which is input into the amplifier to output an amplified control signal; and a controller that performs predetermined control based on the amplified control signal. When the control signal is not input into the amplifier, the amplifier amplifies a voltage signal input from a power source for driving the amplifier.

A power supply control circuit is configured including a MOS-FETconnected between a DC power supplyand a load circuitso that a body diode Dformed between the drain and the source is in a forward direction; and a holding circuitfor maintaining the ON state of the MOS-FETfor a predetermined time when the power supply from the DC power supplyis stopped; where heat generation of the switching element by the surge voltage is suppressed when the surge voltage is generated to prevent breakdown of the switching element while preventing breakdown of internal circuits with respect to reverse connection of the power supply.

An FM-CW radar includes a transmitting section, a mixing section, an A/D conversion section, a storage unit, and a signal processing section. The transmitting section transmits a continuous wave frequency-modulated with a triangular wave. The mixing section mixes the continuous wave transmitted and a reflected wave from a target, to generate a beat wave. The A/D conversion section A/D converts the beat wave into digital data. The storage unit includes a first storage section and a second storage section. The signal processing section reads data from the first storage section to process the read data. The A/D conversion section writes the digital data into the second storage section. The control section switches the first storage section and the second storage section alternately in synchronous with switching between up and down of the triangular wave.
