    Abstract: A radar device transmits an electric wave whose band is spread by a PN code, receives a reflected wave of the electric wave from an object 10, detects correlation between a received signal and a PN code which is delayed, and thereby detects the object. A receiving part 18 connects three receiving antennas 16a.about.16c sequentially one by one, thereby to receive a reflected wave from an object. The three receiving antennas are arranged having their directions so staggered that their antenna beam patterns partly overlap with each other. A correlation detection circuit 19 detects such a slide width that a value of correlation between a received signal received by each of the antennas and the PN code exceeds a predetermined threshold. An operation part 12 obtains an azimuth of an object based on the detected slide width and beam pattern characteristics of the antennas.

    Abstract: A radar device transmits by a transmitting part a wave whose band is spread by a PN code from a PN generator, receives at a receiving part a reflected wave from an object based on the wave and detects the object by detecting correlation between the received signal and the PN code. In this radar device, the received signal which is spread to a wide range is converted to a low-frequency band which is easy to be measured by a down converter so that a signal is generated when correlation is made by a delay of the PN code from a delay circuit, and generates a pulse signal through waveform shaping of the signal to detect the object and to measure its relative speed and distance at a processing part according to the pulse signal and the delay time.

    Abstract: A memory matrix--which comprises memory cells arranged in matrix, each made up of a ferroelectric capacitor and an address selection MOSFET--is divided for each word line into a plurality of memory blocks. Each of the memory blocks is provided with a mode storage circuit that stores a DRAM mode (volatile mode) or an NV mode (non-volatile mode) in one-to-one correspondence for each memory block, and with a refresh operation count circuit that counts for each memory block the number of times the refresh operations is performed consecutively. During an n-th refresh operation (where n is a predetermined number of times), a memory access is made to temporarily change the plate voltage of the ferroelectric capacitor from one voltage to another and at the same time the mode storage circuit is changed from the DRAM mode to the NV mode. When a read or write operation to and from a memory cell in the memory block is performed, the mode storage circuit is changed from the NV mode to the DRAM mode. The refresh operation is omitted for the memory block that was set to the NV mode according to the stored information in the mode storage circuit.
