Radio detection and ranging (radar) adalah piranti yang memanfaatkan gelombang elektromagnetik untuk mengukur jarak benda dan posisi benda. Tipe Radar yaitu continuous wave radar, pulse radar dan pulse Doppler radar. Dalam penelitian ini,tipe pulse radar dengan emitter gelombang nonelektromagnetik untuk memahami prinsip-prinsip radar. Pulsa yang dikirim adalah gelombang ultrasonik diamati karakteristik daya terhadap jarak maksimum, karaktristik ukuran transduser terhadap jarak maksimum, dan karakteristik lebar pulsa terhadap jarak maksimum. Dalam penelitian juga disampaikan mekanisme pengiriman data radar melalui jaringan wireless sensor network(WSN) dengan memanfaatkan transceiver Zig Bee. RadarUltrasonik terdiri dari pemancar dan penerima dikendalikan oleh Arduino Uno dan Xbee Pro. Jarak benda dihitung dengan cara mencari nilai waktu selisih antara waktu pemancar dan waktu menerima, nilai ini sebagai parameter jarak. Kemampuan jarak maksimum Radar Ultrasonik dipengaruhi daya, nilai perubahan akar pangkat empat daya sebanding nilai perubahan jarak maksimum dengan tingkat kesalahan 4 cm pada jarak 210 (16 mm) dan tingkat kesalahan 1.4 cm pada jarak 70 cm (d=8mm). Kemampuan jarak maksimum Radar Ultrasonik dipengaruhi diameter transduser, nilai perubahan pangkat dua diameter transduser sebanding nilai perubahan jarak maksimum dengan tingkat kesalahan 5 cm (d=16 mm dibandingkan d=8 mm). Kemampuan jarak maksimum Radar Ultrasonik dipengaruhi lebar pulsa, nilai perubahan akar pangkat empat jumlah energi dipancarkan sebanding nilai perubahan jarak maksimum dengan tingkat kesalahan 2.8 cm pada jarak 235 cm (d= 16 mm) dan tingkat kesalahan 2.4 cm pada jarak 78 cm(d= 8 mm). Pengujian komunikasi data menggunakan nirkabel Xbee sesuai dengan konfigurasi Xbee dan data tertampil dalam bentuk gambar dan text.

Radio detection and ranging (radar) is a device that utilizes electromagnetic waves to measure the distance of objects and the positionobject. Type Radar is a continuous wave radar, thepulse radar. In this study, the type of pulse radar with wave emitters nonelektromagnetic to understand the principles of radar. Pulses that are transmitted ultrasonic wave power observed characteristics of the maximum distance, Characteristics of transducers to measure the maximum distance, and pulse width characteristics of the maximum distance. In the study also presented data delivery mechanism radar sensor network through a wireless network (WSN) transceivers utilizing Zig Bee. Ultrasonic radar consists of a transmitter and receiver are controlled by an Arduino Uno and Xbee Pro. Object distance is calculated by finding the value of the time difference between the transmitter and the receiving time, the value of the parameter range. The maximum distance capabilities Radar Ultrasonic power is affected, the value of the square root of four power change is proportional to the rate of change of the maximum distance error rate of 4 cm at a distance of 210 (16 mm) and the error rate of 1.4 cm at a distance of 70 cm (d = 8mm). The maximum distance capabilities Radar Ultrasonic transducers are affected diameter, diameter squared value changes the value of the transducer is proportional to the rate of change of the maximum distance error of 5 cm (d = 16 mm compared to d = 8 mm). The maximum distance capabilities are influenced Ultrasonic Radar pulse width, change the value of the square root of four the amount of energy emitted is proportional to the rate of change of the maximum distance error rate is 2.8 cm at a distance of 235 cm (d = 16 mm) and the error rate of 2.4 cm at a distance of 78 cm (d = 8 mm). Testing wireless data communications using XBee and XBee configuration in accordance with the data displayed in the form of images and text
