Abstract:
1. A radar apparatus which transmits a radio frequency transmission signal from a transmitter antenna in a predetermined transmission period, and receives a signal of a reflected wave reflected by a target via a receiver antenna, comprising: a transmission signal generator that generates a first transmission signal obtained by modifying a code having a third sub-code sequence and a fourth sub-code sequence coupled to each other in a first transmission period, and generates a second transmission period obtained by modifying a code having a fifth sub-code sequence and a sixth sub-code sequence coupled to each other in a second transmission period, among first and second sub-code sequences each having a sub-code length obtained by dividing equally a code sequence having a predetermined code length, and third, fourth, fifth, and sixth sub-code sequences obtained by multiplying each of the first and second sub-code sequences by two kinds of different coefficients including a complex coefficient; and a RF transmitter that converts the first and second transmission signals generated by the transmission signal generator into radio frequency transmission signals, and transmits the radio frequency transmission signals from the transmitter antenna.
