Abstract

The invention discloses a continuous pulse radar and its working method. The continuous pulse radar may include: a radar transmitter, used for continuously transmitting a detection pulse signal with a set width at a transmission time interval; a radar receiver, used for transmitting A partial echo signal of the target is received at a pulse time interval between the detection pulse signals; and a signal restorer is used for recovering a complete echo signal based on the partial echo signal. The continuous pulse radar of the present invention takes into account the advantages of traditional pulse radar and continuous wave radar, has the advantages of large average power and high isolation between sending and receiving, reduces peak power, reduces detection blind spots, and has the advantages of low cost and light miniaturization.

Description

A continuous pulse radar and its working method Technical field The present invention relates to technical field of radar, be specifically related to a kind of continuous pulse radar and working method thereof. Background technique Radar is a kind of radio that obtains target information by transmitting detection signals and receiving target reflection signals remote sensing equipment. In the existing technology, the working system of radar can be mainly divided into two working methods: pulse and continuous wave. Mode. Under pulse work mode, radar (also called " pulse radar ") transmits the detection signal of pulse form, then connects Receive the echo signal of the target. Fig. 1 is a schematic diagram of the pulse radar working mode according to the prior art, and the upper part of Fig. 1 is The schematic diagram of the transmitted detection pulse signal, the lower part of Figure 1 is the schematic diagram of the received target echo signal. Radar at t0 The p...
