Problems solved by technology

The disadvantage is that the response time of AGC is relatively long, usually tens of microseconds
Insufficient: The reaction time of APC is longer than that of AGC, because the receiving circuit needs to measure the echo signal and then adjust the transmission power, and the loop is longer

The method comprises the following steps: transmitting a detection signal tothe detection direction and receiving an echo signal of the detection signal, wherein the power of the detection signal comprises first preset power and second preset power, the first preset power ismore than the second preset power, the first preset power is determined by the detection radius and the second preset power is determined by the first preset power and the property of an echo signalreceiver; and analyzing and determining the target object distance in the detection direction according to the echo signal of the detection signal with the first preset power and the echo signal of the detection signal with the second preset power. By implementation of the technical scheme provided by the embodiment of the invention, the effect of improving the validity of the received echo signalcan be achieved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of radar, and in particular, to a radar detection method, device, storage medium, and radar. Background technique [0002] At present, in the long-distance measurement radar, a larger pulse transmission power is generally used to ensure that the echo signal generated by the long-distance target has sufficient energy. However, when detecting short-distance targets, the energy of the echo signal exceeds the upper limit of reception due to excessive power or high reflectivity of the target, causing the receiver to be saturated and unable to measure. [0003] The following two methods are often used to solve the above problems: [0004] 1. An automatic gain control circuit (Automatic Gain Control, AGC) is added to the receiving circuit to automatically adjust the receiver amplification gain according to the strength of the echo signal energy to keep the echo signal energy within the availa...
