Provided is a hostless parking radar system, comprising a main sensor (10), and several slave sensors (20) arranged in parallel, wherein the main sensor (10) comprises a CPU module (12), a first digital pulse module (14), a first ultrasonic unit, and several digital pulse transmission modules arranged in parallel; the slave sensors (20) comprise a second digital pulse module (24), and a second ultrasonic unit; and the several digital pulse transmission modules are respectively in communication with the first digital pulse module (14) and the second digital pulse module (24) by means of bidirectional transmission. The main sensor (10) is provided with the CPU module (12), but none of the slave sensors (20) has a CPU module, thereby substantially reducing the cost of the system. The main sensor (10) communicates with each of the slave sensors (20) using a digital pulse signal, so that the system operates more reliably and more stably.
