A vehicle includes a plurality of transmitters of a code division multiple access (CDMA) radar system to simultaneously transmit a frame of transmit signals. A first duration between transmissions of a first pair of consecutive transmit signals of the transmit signals linearly increases to a second duration between transmissions of a second pair of consecutive transmit signals of the transmit signals. The vehicle also includes a receiver of the CDMA radar system for receiving reflected energy resulting from an object reflecting one or more transmit signals of one or more of the plurality of transmitters. The controller processes the reflected energy to obtain information about the object and controls operation of the vehicle based on the information. 一种载具，包括码分多址(CDMA)雷达系统的多个发射器，以同时发射一帧发射信号。发射信号的第一对连续发射信号的发射之间的第一持续时间线性增加到发射信号的第二对连续发射信号的发射之间的第二持续时间。该载具还包括CDMA雷达系统的接收器，用于接收由物体反射多个发射器中的一个或多个发射器的一个或多个发射信号而产生的反射能量。控制器处理反射能量以获得关于物体的信息，并基于该信息控制载具的操作。
