The new low-LS1 Radar

The new low-speed radar gun Model: LS1 Instrument: 1. Briefly LS1 radar speedometer is a new microwave radar, millimeter-wave and digital signal processing technology, small size, light weight, easy to operate, unique The data interface and state control function, very suitable for the secondary speed product development and systems integration. Unique microwave technology can make a minimum measure to 1 km / h, it is a very high cost of low-speed speedometer. 2. LS1 Radar works in K-band. Doppler principle works: When a bunch of wave encounters a moving object, there will be a return to the wave frequency shift is proportional to the frequency shift of the size and speed of moving objects. Using this principle, we transmit a fixed frequency microwave, then the return signal frequency is measured, which measured frequency shift, frequency shift and velocity through correspondence between the calculated target velocity. 3. Main features and technical specifications: LS1 is a static radar speedometer, tachometer in the process, the radar to be fixed at a certain position and then measure the speed of the target. The measured values ??sent via RS232 serial port. In addition, LS1 limit value can be set based on the user's needs, the maximum rate can save power. When the target speed exceeds the speed limit value, the system will send an instruction signal. Specifications: 1, the working voltage: DC12V 2, Working current: <200mA 3, speed: 1 km / h -110 km / h (0.4m / s-30.5m / s) 4, test distance:> 100m 5, speed range: 2 km / h -99 km / h (0.6m / s-27.5m / s) 6, the data transfer format: ASCII code, three data bits plus a carriage return line feed. 9600 baud, no parity, one start, eight bits, one stop bit. 7, power dissipation: Test Status: <0.5A 10, machine weight: <500g 11, the transmission frequency: 24.15GHz 12, transmit power: 5mW 4. System components of the basic configuration: Host: used to measure the complete speed measurement Results sent 232. In addition to the host: including power lines, data lines, control lines, meter boxes. Option Configuration: a display unit or handheld machine: radar used to detect or set. When none of these options is set by the computer to complete.
